Question

A closed surface contains two equal and opposite charges . How and what will be the net electric flux from the surface?

Answer 1

answer:

Zero.

Gauss’s Law says that

ΦE=qincε0.

The electric flux ΦE through any closed surface is directly proportional to the net inclosed charge qinc.

Becuase the net charge inside the closed surface is zero, the flux is zero.
