a) The electric flux is proportional to the number of electric field lines that penetrate a surface. b) The volume charge density is defined as total charge per unit volume, p = Q/V (C/m²) c) The electric flux is zero when the surface is parallel to the electric field. d) A uniformly charged ring of radius 10 cm has a total charge of 75.0 μC. Therefore, the electric field on the axis of the ring at 30.0 cm from the center of the ring has a magnitude of about 6.39 x 106 N/C, away from the center of the ring. e) A spherical gaussian surface encloses a net charge of -4.0 nC. Therefore, the net electric flux through closed spherical surface is about - 452 N. m²/C
