A charge Q is kept at the centre of a circle of radius r. A test charge q0 is carried from a point X to the point Y on this circle such that arc XY subtends an angle of 60o at the centre of the circle. The amount of work done in this process will be
- \(\frac{1}{4 \pi \varepsilon_0} \frac{\mathrm{Qq}_0}{2 \mathrm{r}}\)
- \(\frac{1}{4 \pi \varepsilon_0} \frac{\sqrt{3} \mathrm{Qq}_0}{2 \mathrm{r}}\)
- Zero
- \(\frac{1}{4 \pi \varepsilon_0} \frac{\sqrt{3} \mathrm{Qq}_0}{\mathrm{r}}\)
Answer
(C) Zero
