AIEEE 2003 | Electrostatics Question 213 | Physics

A thin spherical conducting shell of radius $$R$$ has a charge $$q.$$ Another charge $$Q$$ is placed at the center of the shell. The electrostatic potential at a point $$P$$ a distance $${R \over 2}$$ from the center of the shell is

$${{2Q} \over {4\pi {\varepsilon _0}R}}$$

$${{2Q} \over {4\pi {\varepsilon _0}R}} - {{2q} \over {4\pi {\varepsilon _0}R}}$$

$${{2Q} \over {4\pi {\varepsilon _0}R}} + {q \over {4\pi {\varepsilon _0}R}}$$

$${{\left( {q + Q} \right)2} \over {4\pi {\varepsilon _0}R}}$$
