Surface area of Spherical Shell

Volume of Spherical Shell

A solid conducting sphere of radius a has a net positive charge 2Q . A conducting spherical shell of inner radius b and outer radius c is concentric with the solid sphere and has a net charge -Q . The surface charge density on the inner and outer surfaces of the spherical shell will be

A positive charge Q is placed at the centre O of a thin metalic spherical shell. Select the correct statements from the following: (i) The electric field at any point outside the shell is zero (ii) The electrostatic potential at any point outside the shell is (Q)/(4 pi epsilon_(0) r) , where r is the distance of the point from O (iii) The outer surface of the spherical shell is an equipotential surface (iv) The electric field at any point inside the shell , other than O , is zero

A particle of mass M is at a distance a from surface of a thin spherical shell of equal mass and having radius a .

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

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.
