The correct option is (d). The electric field’s flux via a fastened surface because of all the charges is equal to the flux because of the surface charges bounded.
Explanation:
- On the close surface, the flux’s contribution due to the charges on the outside surface is zero.
- This is because of the fact that the number of lines in the field moving out of the surface is equal to the number of field lines moving into the closed surface.
- So, outside the closed surface, the net contribution of the charge is zero. The counting contribution is just because of the charges that are within the closed surface.
- Thus, the electric field’s flux due to all charges via a closed surface is equal to the flux that appears because of the close surface’s charges.
