A point charge 'Q' is placed at the centre of a spherical cavity of radius 'b' carved inside a solid conducting sphere of radius 'a'. Then total energy of the system is:
`[k = (1)/(4pi in_(0))]`

A charge Q is uniformly distributed inside a non- conducting sphere of radius R . Find the electric potential energy stored in the system.

A point charge +q is placed at the centre of a conducting spherical shell of inner radius a and outer radius b. Find the charge appearing on the inner and outer surface of the shell.

A point charge +q is placed at the centre of a conducting spherical shell of inner radius a and outer radius b. Find the charge appearing on the inner and outer surface of the shell.

A conducting sphere of radius b has a spherical cavity with its centre displaced by 'a' from centre of sphere O_(1) . A point charged q is placed at the centre of cavity O_(2) . Q charge is given to conducting sphere and charge q_(0) is placed at P, a distance c from centre O_(1) . Further O_(1), O_(2) and P are collinear
