Question

Find the electric field at point P (as shown in figure) on the perpendicular bisector of a uniformly charged thin wire of length L carrying a charge Q. The distance of the point P from the centre of the rod is $a=\frac{\sqrt{3}}{2} L$.

Select the correct option:

A

$\frac{\sqrt{3} Q}{4 \pi \varepsilon_0 L^2}$

B

$\frac{\mathrm{Q}}{3 \pi \varepsilon_0 L^2}$

C

$\frac{Q}{2 \sqrt{3} \pi \varepsilon_0 L^2}$

D

$\frac{Q}{4 \pi \varepsilon_0 L^2}$

✓ Correct! Well done.
