Refer to the arrangement of charges in the figure and a Gaussian surface of radius R with Q at the centre. Then a) total flux through the surface of the sphere is –Q/ε0 b) field on the surface of the sphere is –Q/4πε0R2 c) flux through the surface of the sphere due to 5Q is zero d) field on the surface of the sphere due to -2Q is the same everywhere
