(a) If an electric dipole is inside a hollow sphere then what is the flux through the surface of the sphere. (b) Using Gauss’ law derive an expression for electric field due to a uniformly charged thin spherical shell at an outside point.
(c) What is the flux through the surface of a hollow sphere of radius R which encloses a charge Q and how would the flux through the surface change if a medium of dielectric constant k is introduced inside the sphere in place of air.
OR
(a) Define electric potential.
(b) Calculate electric potential V due to a point charge Q at a distance r from it. Draw then graph showing variation of potential with distance due to a point charge.
(c) Calculate the potential on the surface of hydrogen atom of radius 0.5Å.
