Question

Two circles are drawn with centre at a charge +q now a small test charge from point a

Answer 1

Pls complete your question

• it is incomplete

Answer 2

The work done on the two circles will be 0

Explanation:

The potential at any point on the circumference is equal. It means the circle surface will represent a equipotential surface.

So change in potential at two point on surface is zero i.e dV=0

The work done =qdV=0
