The net outward flux through the box is zero.
According to Gauss' Law, the electric flux through a closed surface is equal to the net charge enclosed by the surface divided by the permittivity of free space. Since the two charges are inside the box, the net charge enclosed by the box is equal to the sum of the charges q1 and q2.
However, since the box is closed, the outward flux due to one charge is cancelled by the inward flux due to the other charge. This cancellation occurs because the electric field lines emerging from one charge enter the box and terminate on the other charge, resulting in a net flux of zero.
Therefore, the net outward flux through the box is zero.
Two charges q subscript 1and q subscript 2are inside a closed cubical box of side a .
