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 at the center of spherical shell?

The radius of gyration of a spherical shell about its diameter is :

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

State Gauss's theorem with the help of diagram, derive an expression for the electric field intensity due to uniformly charged thin spherical shell at a point on the surface of the 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 :
