The electric potential at centre of metallic conducting sphere is

Question

The electric potential at centre of metallic conducting sphere is (A) zero (B) half from potential at surface of sphere (C) equal from potential at surface of sphere (D) twice from potential at surface of sphere

Tardigrade Admin · Accepted Answer

Inside a charged sphere, electric field intensity at all points is zero and electric potential is same at all the points. Electric potential,

V = \frac{1}{4 π ε _{0}} \frac{q}{R}

Therefore, potential at the centre is equal to the potential at the surface.

Q. The electric potential at centre of metallic conducting sphere is

zero

half from potential at surface of sphere

equal from potential at surface of sphere

twice from potential at surface of sphere

Inside a charged sphere, electric field intensity at all points is zero and electric potential is same at all the points. Electric potential, V=4πε0​1​Rq​ Therefore, potential at the centre is equal to the potential at the surface.
