Question

Work done in carrying an electric charge Q1 once round a circle of radius R with a charge Q 2 at the center of the circle is (A) ( Q 1 Q 2/4 π ε 0 R ) (B) ∞ (C) ( Q 1 Q 2/4 π ε 0 R ) (D) Zero

Electrostatic force is a conservative force so work done in carrying an electric charge Q, once around a circle of radius R will be zero

Q. Work done in carrying an electric charge $Q_{1}$ once round a circle of radius $R$ with a charge $Q_{2}$ at the center of the circle is

$\frac{Q _{1} Q _{2}}{4 π ε _{0} R}$

$\infty$

$\frac{Q _{1} Q _{2}}{4 π ε _{0} R}$

Zero
