# 2.4) A spherical conductor of radius 12 cm has a charge of  distributed uniformly on its surface. What is the electric field (c) at a point 18 cm from the centre of the sphere?

Given,

Charge on the conductor

The radius of the spherical conductor

NOW,

the electric field at point 18cm away from the centre of the spherical conductor is given by:

Hence electric field at the point 18cm away from the centre of the sphere is
