Two infinitely large charged planes having uniform suface charge density `+sigma` and `-sigma` are placed along `x-y` plane and `yz` plane respectively as shown in the figure. Then the nature of electric lines of forces in `x-z` plane is given by:

Options

A.
B.
C.
D.

Answer

c

Explanation

The electric filed intensity due to each uniformly charged infinite plane is uniform. The electric field intensity at points `A,B,C` and `D` due to plane `1`, plane `2` and both planes are given by `E_(1),E_(2)` and `E` as shown in figure 1. Hence the electric lines of forces are as given in figure 2.
