Question
Among identical spheres A and B having charges −15C and −16C:
✓

Answer

  1. −15C is at higher potential.
Explanation:
Potential at surface of a sphere of radius r is V = kQ/ r
As identical sphere so r is same for both, Thus V will depend on charge Q.
So when Q is more, potential will be more.
Since −15 C is more than −16 C, so −15 C sphere will have higher potential.
