2. Electric Potential and Capacitance
easy

Charge $q_{2}$ is at the centre of a circular path with radius $r$. Work done in carrying charge $q_{1}$, once around this equipotential path, would be

A

$\frac{1}{4 \pi \varepsilon_{0}} \times \frac{q_{1} q_{2}}{r^{2}}$

B

zero

C

$\frac{1}{4 \pi \varepsilon_{0}} \times \frac{q_{1} q_{2}}{r}$

D

infinity
