A conducting sphere of radius R is given a charge Q. What is the electric field and the electric potential at the centre of the sphere?
Answer & explanation
Correct answer: option 3
The correct answer is Option (2) → zero and $\frac{Q}{4πε_0R}$
As all the charge would get distributed on the surface. The net charge inside sphere is zero.
and,
As this sphere is an equipotential surface, $\frac{Q}{4πε_0R}$ at the center of sphere.
