A conducting sphere of radius R is given a charge Q. The electric potential and the electric field at the center of the sphere respectively are:
  1. Zero and Q4πε0 R2
  2. Q4πε0 R and Zero
  3. Q4πε0 R and Q4πε0 R2
  4. Both are zero

Solution

This is a learning based question where we have to choose the option which is correct for the electric potential and electric field at the centre of the sphere.

For a conducting sphere
Electric field at centre =0
Potential at centre =kQR=Q4πε0 R

So Option (2) will be correct.
