Question

Find the flux of the electric field through a spherical surface of radius R due to a charge of 10^-7C at the centre and another equal charge at a point 2R away from the centre (figure 30-E2).

Answer 1

Given: Magnitude of the two charges placed = 10^–7c.
We know: from Gauss’s law that the flux experienced by the sphere is only due to the internal charge and not by the external one.
