Why electric field intensity inside hollow spherical charged conductor is zero
What is the unit of intensity of electric field?
What happens when there is a cavity inside a conductor?
A solid conducting sphere of radius is surrounded by a thin uncharged concentric conducting shell of radius . A point charge is placed at a distance from common centre of conducting sphere and shell. The inner sphere is then grounded.
