A thin spherical shell is charged by some source. The potential difference between the two points $C$ and $P$ (in $V$) shown in the figure is; (Take $\frac{1}{4\pi\epsilon_0}=9\times10^{9}$ SI units, $R=3$ cm, $q=1\mu C$)

A $0.5\times10^5$
B zero
C $3\times10^5$
D $1\times10^5$

The answer is B.

Solution

The electric potential due to a uniformly charged spherical shell is constant everywhere inside the shell and equal to its value on the surface. Hence $V_C = V_P$ $\therefore$ Potential difference = 0
