This electric force calculator will enable you to determine the repulsive or attractive force between two static charged particles. Continue reading to get a better understanding of Coulomb's law, the conditions of its validity, and the physical interpretation of the obtained result.
How to use Coulomb's law
Coulomb's law, otherwise known as Coulomb's inverse-square law, describes the electrostatic force acting between two charges. The force acts along the shortest line that joins the charges. It is repulsive if both charges have the same sign and attractive if they have opposite signs.
Coulomb's law is formulated as follows:
F = keq₁q₂/r²
where:
F is the electrostatic force between charges (in Newtons),
q₁ is the magnitude of the first charge (in Coulombs),
q₂ is the magnitude of the second charge (in Coulombs),
r is the shortest distance between the charges (in m),
ke is the Coulomb's constant. It is equal to 8.98755 × 10⁹ N·m²/C². This value is already embedded in the calculator - you don't have to remember it :)

Any experiment on Earth involving natural motion will provide direct evidence that gravity pulls objects straight down. They should use it. Any experiment on Earth involving natural motion will provide direct evidence that gravity pulls objects straight down. They should not use it. The experiment has several dimensions of motion, including one parallel to the ground, so the motion of the ball does not directly test the force of gravity. They should not use it.

The experiment shows the ball falls toward the bottom of the hill, so it provides direct evidence that gravity pulls an object downward. They should not use it. Gravity should be tested in space, and this experiment could only be tested on Earth.
The ball raised up the hill is given gravitational potential energy, which
causes it to roll spontaneously down the hill.
The statement that explains whether the ball rolling down the hill
experiment should be used is; The experiment shows the ball falls toward
the bottom of the hill, so it provides direct evidence that gravity pulls an
object downward. They should use it.
Reason:
The equation for the velocity of a ball falling down a hill is [tex]v = \sqrt{\dfrac{10}{7} \cdot g \cdot h}[/tex]
Therefore, by increasing the height from which the ball rolls down the hill,
the velocity of the ball increases, which indicates that the ball is
accelerating, and therefore, being acted on by a force, the force of gravity.
Therefore;
Given that the ball falls or moves with increasing speed towards
the bottom of the hill, which shows that the motion is due to Earth's pull
known as the gravitational force, the experiment should be used.

Q1. A 130 N horizontal force keeps a 30 kg chair moving at a constant velocity. Find the
coefficient of kinetic friction between the chair and the floor.
The coefficient of kinetic friction between the chair and the floor is 0.442.
The given parameters;
horizontal force on the chair, F = 130 Nmass of the chair, m = 30 kgThe normal force on the chair is calculated as follows;
Fₙ = mg
Fₙ = 30 x 9.8 = 294 N
The frictional force between the chair and the floor is calculated as follows;
Fk = μFₙ
The net force on the chair is calculated as follows;
[tex]\Sigma F_x = 0\\\\F- \mu_k F_n = 0\\\\130 - \mu_k (294) = 0\\\\\mu_k = \frac{130}{294} \\\\\mu_k = 0.442[/tex]
Thus, the coefficient of kinetic friction between the chair and the floor is 0.442.

a proton, moving east, enters a magnetic field of a certain strength. because of this field the proton curves downward. what is the direction of the magnetic field?
Answer:
F = q V X B
Using the right hand rule (right hand screw) turn V into B to get direction of force which in this case is down
If V is east and F is down then one can see that B must be directed towards the south - turn V into B (south) and F will be directed downwards.
what is concentration?
Answer:
The concentration of a chemical substance expresses the amount of a substance present in a mixture.
Another definition is that concentration is the ratio of solute in a solution to either solvent or total solution. Concentration is usually expressed in terms of mass per unit volume.
Answer:
In chemistry, concentration is the abundance of a constituent divided by the total volume of a mixture. Several types of mathematical description can be distinguished: mass concentration, molar concentration, number concentration, and volume concentration.

People who are exceptionally tall (like seven feet and over) often have a disorder that causes them to keep growing past the age most people do in their late teens. What gland would this disorder be associated with?
A.
adrenal
B.
thyroid
C.
pituitary
D.
pancreas
Answer:
C is the answer
Explanation:
The pituitary gland also known as the Master gland controls and regulates secretion of most hormones, when taller people usually grow past expected height this is normally due to the Pituitary gland not properly regulating and it secretes too many growth hormones causing "gigantism."

An object is travelling at a velocity of 5m/s to the right for 5 seconds. If NO forces are applied to the object, what will the velocity of the object be after 5 seconds.
Answer:
Below
Explanation:
We can use this formula to find the final velocity of the object :
vf = vi + at
Now, because no force is applied to the object, the acceleration of this object will be 0 according to Newton's 1st law!
vf = 5m/s + (0)(5)
vf = 5 m/s

which layer of the atmosphere has no definite outer limit?
To solve this, we must be knowing each and everything related to atmosphere. Therefore, thermosphere is the layer of the atmosphere has no definite outer limit.
What is atmosphere?
The atmosphere is more than simply the beautiful sky above. The atmosphere is made up of numerous levels of gases that surround the planet.
The word "atmo," which meaning vapor, smoke, or fog in Greek, is the source of the atmosphere's name. "Sphere" comes from the Greek word sphaira, which meaning ball. The term "atmosphere" refers to a vapor ball. Thermosphere is the layer of the atmosphere has no definite outer limit. The thermosphere is located between 53 miles (85 kilometers) and 375 mile (600 kilometers).
Therefore, thermosphere is the layer of the atmosphere has no definite outer limit.

The exosphere is the layer of the atmosphere that has no clear outer limit. The exosphere is the Earth's atmosphere's outermost layer, extending from the top of the thermosphere to the edge of space.
The exosphere, unlike the other layers of the atmosphere, gradually transitions into the vacuum of outer space with no clearly defined border.
The density and spread out of gas molecules in the exosphere are exceedingly low.
This area is made up mostly of relatively light gases like hydrogen and helium, and it is where satellites and other spacecraft circle the Earth.
Thus, the progressive reduction in density as the atmosphere merges into space accounts for the lack of a well-defined outer boundary.

A 1,336 kg car drives around a flat 199-m-diameter circular track at 22 m/s. What is the
magnitude of the net force on the car?
Hi there!
This is an example of Uniform Circular Motion, thus:
Net Force = Centripetal force
∑F = mv²/r
Plug in the given values. Remember to convert from diameter to radius, first.
d = 199m
r = d/2 = 199/2 = 99.5 m
∑F = 1336(22²)/99.5 = 6498.73 N

A 2300-kg car slows down at a rate of 3.0 m/s2 when approaching a stop sign. What is the magnitude of the net force causing it to slow down?
The magnitude of the net force causing the 2300kg car to slow down is 6900N
HOW TO CALCULATE FORCE:
The net force applied on a moving object can be calculated by multiplying the mass of the object by its acceleration. That is;Force (N) = mass (kg) × acceleration (m/s²)According to this question, a 2300-kg car slows down at a rate of 3.0 m/s2 when approaching a stop sign. The net force causing the car to stop can be calculated as follows:F = 2300kg × 3m/s²
F = 6900N
Therefore, the magnitude of the net force causing the 2300kg car to slow down is 6900N.Learn more at: https://brainly.com/question/18109210?referrer=searchResults
