In the figure, a very large plane sheet of positive charge is shown. `P_1` and `P_2` are two points at distance l and 2l from the charge distribution. If `sigma` is the surface charge density, then the magnitude of electric fields `E_1` and `E_2` at `P_1` and `P_2` respectively are :

Options

A. `E_1=sigma//epsi_0,E_2=sigma//2epsi_0`
B. `E_1=2sigma//epsi_0,E_2=sigma//epsi_0`
C. `E_1=E_2=sigma//2epsi_0`
D. `E_1=E_2=sigma//epsi_0`

Answer

C

Explanation

Electric field due to a large non–conducting sheet
`E=(sigma)/(2epsi_0)` and it is uniform width distance from the sheet
