Question

A point charge Q has been placed at a point outside a neutral spherical conductor. The induced charge density at point P on the surface of the conductor is -sigma The distance of point P from the point charge Q is 2R (where R is radius of the conductor). Find the magnitude and direction of electric field at a point outside the conductor that is very close to its surface near P.
