Question 703: Electrostatics & Capacitance

Question

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 $$\frac{1}{4 \pi \varepsilon_0}=9 	imes 10^9$$ SI units)

Accepted Answer

For uniformly charged spherical shell,
$$\begin{aligned}
& V=\frac{k q}{R} \quad(	ext { For } r \leq R) \
& 	herefore \quad V_C=V_P \
& V_C-V_P=	ext { Zero } \
\end{aligned}$$
