Question

if E.ds=0, inside a surface, that means:-
(a)there is no net charge present inside the surface
(b) uniform electric field inside the surface
(c) discontinues field lines inside the surface
(d) charge present inside the surface

Answer 1

option 1 is correct...........

Answer 2

If E.ds=0, inside a surface, that means there is no net charge present inside the surface.

Why net charge inside is zero?

• The net charge within the surface must be zero. As a result, all additional charges must be external to the surface. This is due to the fact that charges outside the surface have no effect on the electric flux.
