Two infinite sheets having charge densities σ1 and σ2 are placed in two perpendicular planes whose two-dimensional view is shown in figure. The charges are distributed uniformly on the sheets in electrostatic equilibrium condition. Four points are marked I, II, III and IV. The electric field intensities at these points are E→1 , E→2, E→3 , and E→4, respectively. The correct expression for the electric field intensities is

The electric field E1 at one face of a parallelopiped is uniform over the entire face and is directed out of the face. At the opposite face, the electric field E→2 is also uniform over the entire face and is directed into that face (as shown in figure). The two faces in question are inclined at 30∘ from the horizontal, E→1 and E→2(both horizontal) have magnitudes of 2.50×104NC−1 and 7.00 × 10^4 N/C. respectively. Assuming that no other electric field lines cross the surfaces of the parallel lopiped, the net charge contained with in is
