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 -

Figure

Show answer and solution

Answer: (a)

  1. Inside the shell E=0E = 0, so V=kQRV = \frac{kQ}{R} is constant from OO to AA (r≤Rr \le R).
  2. Outside V=kQrV = \frac{kQ}{r}, a smooth 1/r1/r fall towards zero.
  3. Graph (a) is flat up to r=Rr = R then falls as 1/r1/r, so the answer is (a).
