A5 cm radius conducting sphere has a charge density of o 2.0 x 10- c/m2 on its surface choosing the potential at infinity to be zero, what is the electric potential v at its surface? a) v 1.1 x 10 v b) v 2.2 x 104 v c) v 2.3 x 105 v d) v 3.6 x 105 v

Potential at the surface of the conducting sphere: 1.1 × 10⁴ V.

Given that:

Explanation:

By applying Gauss Law, the electrical field outside a uniformly charged sphere is the same as if all the charge on it were concentrated at a point charge at the center of the sphere.

Surface area of this sphere:

.

Charge on the sphere:

.

Electrical potential at the surface of the sphere, as if the sphere is a point charge:

.

the answer is a. at the equator
