Electric Potential & Equipotentials

For a uniformly charged thin spherical shell, the electric potential (V) radially away from the centre (O) of shell can be graphically represented as -

Show answer and solution

Answer: (a)

Inside the shell $E = 0$ , so $V = \frac{kQ}{R}$ is constant from $O$ to $A$ ( $r \le R$ ).
Outside $V = \frac{kQ}{r}$ , a smooth $1/r$ fall towards zero.
Graph (a) is flat up to $r = R$ then falls as $1/r$ , so the answer is (a).
