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 `1/(4 pi epsilon_0` = 9 × 10⁹ SI units)

Options

• 0.5 × 10⁵

• zero

• 3 × 10⁵

• 1 × 10⁵

Answer 1

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 zero.

Explanation:

The electric potential due to a uniform charged spherical shell is constant everywhere inside the shell, and its value is equal to that on the surface of the shell.

Hence,

V_c = V_p

∴ Potential difference = 0
