Q. 5

The electric fiel

Answer :

Let the total charge on the sphere be = Q.

The sphere is uniformly charged.


Charge density = ρ

... (1)

The electric field at a distance 2 R due to the sphere = E

... (2)

To Find: Electric field at a distance R/2 from the centre of sphere = E1

First, we find the charge enclosed within the sphere of radius R/2.

Q1 = charge enclosed
