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: Option 1) Zero and  Option 2) $\frac{\text{Q}}{4\pi\epsilon_{\text{o}}\text{R}}$ and Zero Option 3) $\frac{\text{Q}}{4\pi\epsilon_{\text{o}}\text{R}}$ and  Option 4) Both are zero

As discussed (Concept missing)

For conducting sphere,

Potential at the center=Potential on the sphere

=$\frac{1}{4\pi \varepsilon _{o}} \: \frac{Q}{R}$

Electric field at the centre=0

Option 1)

Zero and

This option is incorrect

Option 2)

$\frac{\text{Q}}{4\pi\epsilon_{\text{o}}\text{R}}$ and Zero

This option is correct

Option 3)

$\frac{\text{Q}}{4\pi\epsilon_{\text{o}}\text{R}}$ and

This option is incorrect

Option 4)

Both are zero

This option is incorrect
