Answer:

3Q / 4 pi (R^3 - r^3)

Explanation:

Charge density = charge / volume

volume of a spherical shell = [tex]\frac{4}{3} \pi(R^{3} - r^{3})[/tex]

(a) The charge density of the spherical shell is ³/₄ x πQ(R³ - r³).

(b) The charge density inside the conducting sphere is zero.

What is Charge density?

Charge density is the amount of electric charge per unit length, surface area, or volume of a given object.

σ = Q/V

where;

  • V is the volume of the shell
  • Q is the charge on the surface

The volume of the spherical shell is calculated as follows;

V = ³/₄πR³ - ³/₄πr³

V = ³/₄π(R³ - r³)

Charge density = Q/V

                          = ³/₄ x πQ(R³ - r³)

Charge density inside the conducting sphere

The charge density inside the sphere is zero.
