Find the initial charges on the sphere.

**Q.**

Two identical conducting spheres carrying different charges attract each other with a force F when placed in air medium at a distance d apart. The spheres are brought into contact and then taken to their original positions. Now the two spheres repel each other with a force whose magnitude is equal to that of the initial attractive force. The ratio between initial charges on the spheres is

Solution Verified by Toppr

Correct option is D)

Potential energy between any two given particles= r kq 1 q 2

since revolving in circle does not change the distance r between these charges, will be equal to zero

hence work done=0
