Dear student

It is based on the following principles:

1) Action of sharp points: Charges are leaked from pointed ends of charged conductors. This creates an electric wind (as moving air is ionized) which moves away from the conductor.

2) The property that the charge given to a hollow conductor is transferred to the outer surface and is distributed uniformly on it.

Hope this helps.
