Question

Potential (V) due to a charged conducting hollow spherical shell varies with distance (r) from centre as

• A.
• B.
• C.
• D.

Answer 1

The correct option is B

$V_{inside}=\frac{Q}{4\pi {ϵ}_{0}R}$ for $r\le R$ ....... (i)
and $V_{out}=\frac{Q}{4\pi {ϵ}_{0}r}$ for $r\ge R$ ...... (ii)
i.e. potential inside the hollow spherical shell is constant and outside varies as $V\propto \frac{1}{r}$.
