The maximum charge that can be conveyed to a conducting sphere of diameter 20 cm (breakdown field of air `= 2xx10^(6) Vm^(-1))` is

A conducting sphere of radius 10 cm is given a charge of +2xx10^(-8)C . What will be its potential?

Statement-1: The maximum charge that can be given to a conductor of fixed volume depends on its shape. Statement-2: If the electric field near the condutor is sufficient for dielectric breakdown of air, no more charge can be transferred to it.
