# Conducting a Spherical Force Test

SATPHY-4LQJKX

Two identical conducting spheres were situated so that they were insulated from their surroundings, and their centers were separated by a distance, $d$.

One sphere had a charge of $+8$ Coulombs; the other had a charge of $–4$ Coulombs.

The spheres were then brought together to touch each other. The spheres were separated and again insulated from their surroundings, and their centers were separated by a distance, $d$.

How does the magnitude of the electrostatic force between the spheres in their final situation compare to the magnitude of electrostatic force between them in their original situation?

A

The magnitude of the final force is the same as the magnitude of the original force.

B

The magnitude of the final force is half as much as the magnitude of the original force.

C

The magnitude of the final force is twice as much as the magnitude of the original force.

D

The magnitude of the final force is one-fourth as much as the magnitude of the original force.

E

The magnitude of the final force is one-eighth as much as the magnitude of the original force.
