Volume of Spherical Shell

The volume of a spherical shell whose external and internal diameters are 14 cm and 10 cm respectively :

Surface area of Spherical Shell

What is the intensity of gravitational field of the centre of a spherical shell

Shown in the figure a spherical shell with an inner radius 'a' and an outer radius 'b' is made of conducting metarial. A charge +Q is placed at the centre of the spherical shell and a total charge -q s placed on the shell. Charge -q is districuted on the surfaces as :

The outer diameter of a spherical shell is 12 cm and its inner diameter is 8 cm. Find the volume of metal contained in the shell. Also, find its outer surface area.

A body of mass m is placed at the centre of the spherical shell of radius R and mass M. The gravitation potential on the surface of the shell is
