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 field 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. Figure 2.

Aliter:
Electric lines of forces orginatc from positively charged plane. Hence the correct representation of ELOF is given figure 2.
