Question

The work done in moving a $500\mu c$ charge between two points on equipotential surface is :

• A. zero
• B. finite positive
• C. finite negative
• D. infinite

Answer 1

The correct option is A zero

The equipotential surface means that the potential at every point is same. So the potential difference between two points on the equipotential surface will be zero.
Work done $=$charge $\times$ potential difference $=qdV=0$
