Two identical conducting balls A and B have charges -Q and +3Q respectively . They are brought in contact with each other and then separated by a distance d apart. Find the nature of the coulumb force between them.

Text Solution

Verified by Experts

Charge on either sphere after sharing =+Q. Hence force between them is repulsive in nature.
