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:
A
Zero and $\frac{Q}{4\pi\varepsilon_0R^2}$
B
$\frac{Q}{4\pi\varepsilon_0R}$ and Zero
C
$\frac{Q}{4\pi\varepsilon_0R}$ and $\frac{Q}{4\pi\varepsilon_0R^2}$
D
Both are zero
Detailed Solution
At the centre of a charged conducting sphere, $E = 0$ and $V = \frac{Q}{4\pi\varepsilon_0R}$.
