. Because the same type of charge is on each sphere, the force is repulsive. As expected, the force between the charges is greater when they are 3.0 cm apart than when they are 5.0 cm apart.
How is the force between two charges affected when each charge is doubled and distance between them is also doubled?
The size of the force varies inversely as the square of the distance between the two charges. Therefore, if the distance between the two charges is doubled,

How will the force between two charged spheres be changed if the distance between the spheres centers is reduced to half its original value?
Explanation: The force between the two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. Hence, if distance between charges is halved (charges remaining kept constant),
the force between the two charges is quadrupled
.

the electromagnetic force
, one of the four fundamental forces (or interactions) of nature.
What happens when two charged conducting spheres touch?
When the two conducting spheres are brought together to touch, it is as though
they become one single big conductor and the total charge of the two spheres spreads out across the whole surface of the touching spheres
. When the spheres are moved apart again, each one is left with half of the total original charge.
What is the force of gravity on the sphere?
The gravitational force on an object
within a hollow spherical shell is zero
. The gravitational force on an object within a uniform spherical mass is linearly proportional to its distance from the sphere’s center of mass (COM).
Explanation:
Electrostatic force is directly related to the charge of each object
. So if the charge of one object is doubled, then the force will become two times greater.
How do you write Coulomb’s law in vector form?

…
What is the charge on each sphere?
| Q 1 = Q 2 = −6 μC = −3 μC | 2 |
|---|
Solution by consideration. If we electrically connect two balls, the charge on the balls would redistribute, so the potential on the
both balls is the same
. The potential on the ball is the same as the point charge potential. It is directly proportional to the charge and inversely proportional to the ball radius.
Is the force the same for both spheres or different?
In the case of gravity near the earths surface, the force on an object that has a mass “m” is “mg”, that is, the mass of the object times the constant “g”. … Because the metal spheres in your problem are the same size and shape, the air resistance force on
them will be the same
(if they are falling at the same speed).
How do you find the force of a charge?
The force on the charge is given by
F = qE
, the same way the force on the mass m is given by F = mg.
How do you calculate the force between two charges?
To compare the two forces, we first compute the electrostatic force using Coulomb’s law,
