Q.
A conducting sphere of radius $R$ is given a charge $Q$ . The electric potential and the electric field at the centre of the sphere respectively are [2014]

1 zero and $\frac{Q}{4 π ε_{0} R^{2}}$

2 $\frac{Q}{4 π ε_{0} R}$ and zero

3 $\frac{Q}{4 π ε_{0} R}$ and $\frac{Q}{4 π ε_{0} R^{2}}$

4 both are zero

Ans.
(2)

For the conducting sphere,

Potential at the centre = Potential on the sphere = $\frac{1}{4 π ε_{0}} \frac{Q}{R}$

Electric field at the centre = 0
