Question

why cant we take area vector in electric flux as inward in closed surface​

Answer 1

Answer:

• Net Positive charge can be present inside the sphere and the area vector of the plane might be in opposite direction to that of field.

• There could be more no.of negative charges compared to the positive charges enclosed by the surface

• There could be only negative charges present inside the sphere.

• Charges could be even completely absent inside the sphere.

• Flux through a surface need not to be contributed only due to charges present inside in the sphere, the charges present outside the sphere can also contribute flux.

• Flux is basically no.of field lines passing through an surface and it doesn’t necessarily mean that the charges must be enclosed by the surface(given by gauss ’s law exception- flux can be present through certain part of the closed surface even if q enclosed is zero).
