From this paper

a.
State Gauss’s theorem (3 marks) (b) An insulating solid sphere of radius a has a uniform volume charge density ρ and carries a total positive charge Q. Calculate the magnitude of the electric field at a point: (i) outside the sphere (6 marks) (ii) inside the sphere (7 marks) (iii) Do we have the same value for the electric field at the surface of the sphere? Justify your answer (4 marks)
