Question 1 of 5

Consider an infinite long hollow pipe of radius R carrying a surface charge density $\sigma$ and is rotated about its central axis with an angular speed $\omega$ . Choose the correct expression of vector potential at a distance r<R from its axis.

A

$\frac{\mu_{0} \sigma \omega R r}{2}$

B

$\frac{\mu_{0} \sigma r}{2 \omega R}$

C

$\frac{\mu_{0} \sigma \omega r}{2 R}$

D

$\frac{\mu_{0} \sigma R r}{2 \omega}$
