Step 1
a) The charge enclosed by the Gaussian surface in terms of volume charge density and the radius of the sphere is,
The volume of the sphere is as follows:
Here, R is the radius of the sphere.
Substitute
Step 2
The area of the surface element is,
Here, r is the distance from the charge to the field point.
The electric field is calculated by using the Gauss’s law.
Substitute
Solve the above equation for electric field inside the sphere.
Step 3
b) The radius of the cavity is
The net electric field in the cavity is equal to the difference between the electric field due to the remaining hollow sphere and the electric field due to charge filling cavity. So, the net electric field inside the cavity is,
Substitute
