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?
Charge on the conductor
The radius of the spherical conductor
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
