Question

Electric potential at a point $P$ which is at a distance $r=\frac{R}{2}$ from centre where $R$ is the radius of uniformly charged shell with surface charge density $\sigma$ is

• A. Zero
• B. $\frac{\pi R\sigma }{{\epsilon }_0}$
• C. $\frac{\sigma R}{{\epsilon }_0}$
• D. $\frac{\sigma }{2{\epsilon }_0}R$

Answer 1

The correct option is C $\frac{\sigma R}{{\epsilon }_0}$

Potential inside the shell is constant.
