What happens to the electrical capacitance of a conductor when it is brought closer to an earthed conductor?

Obtain an expression for the capacitance of a spherical conductor.

A test charge q_0 is placed at the centre of a spherical conductor of radius R. A charge Q is placed on the spherical conductor, What will be electrostatic force on the conductor due to q_0

If the current in a conductor is doubled, the rate of rise of temperature in the conductor will be assuming that there is no loss of heat from the conductor.
