Grade 12Electrostatics
How many electrons must be removed from a neutral metal sphere so that it acquire charge +1 nC? If the radius of the sphere is 0.05 m, calculate (i) surface density of charge on the sphere (ii) electric intensity at a point outside and close to the surface of the sphere and (iii) electric intensity at a point of distance 0.08 m from the centre of the sphere
