Question

what is the electric flux through a cube of side 1 cm which encloses an electric dipole

Answer 1

the net electric charge inside the closed cubic surface = 0, as the dipole consists of equal and opposite charges.

The net electric flux through a closed 3-d surface = charge enclosed/epsilon.

So  net electric flux = 0.

Answer 2

Hey !!

Zero ( as net charge enclosed by the surface is zero ).

DETAILED EXPLANATION

In a cubic surface, the net electric charge will be zero since dipole carries equal and opposite charges. It is observed that the net electric flux through closed surface will be

                                         = Charge enclosed / ε₀

and because the charge enclosed is zero.

  electric flux is also zero.

Good luck !!
