If the same charge of Q coulomb as in part above is given to a spherical conductor of the same radius R, what will be the energy of the system?

A charge Q coulomb is uniformly distributed over a sphere volume of radius R metres. Obtain an expression for the energy of the system.

A non-spherical hollow conductor is given a charge Q. What is the electric field in the cavity?

If a point charge be rotated in a circle of radius r around a charge q. what will be the work done?

A charge Q is given to a conducting cone. Is electric potential at all the points on the surface of the cone same?

In an electric field the work done in bringing a 2 coulomb charge from infinity to a point a is 10 joules and in bringing the same charge to some another point B is 20 joule find the potential difference between two points A and B what would be the work done if the same charge is brought directly from A to B.

A charge Q is given to a conducting cone. Is charge density on the cone it all the points is same?

A charge Q isenclosed by a Gaussian spherical surface of radius R. If the radius is doubled, then the outward electric flux will
