Question

Two identical isolated conducting spheres are picked for an experiment. Only one of them is charged. If the spheres are now briefly brought into contact and then separated by a small distance, the two spheres would experience
A) a force of repulsion, because they are like-charged.
B) a force of attraction, because they are oppositely charged.
C) no force, because charges are not transferred by mere contact.
D) no force, because the distance separating the spheres needs to be large.

Answer 1

a force of repulison, because they are like charged

Answer 2

Answer:

The answer to this question is the option “A” that states “a force of repulsion, as they are like charged.”

This is because when two identical and isolated spheres of which one is charged, and the other one is neutral are brought into contact with each other the charge on the charged sphere is distributed equally in the neutral sphere, and it also gets charged.

As they have the same charges, they will repel each other.
