In the figure, a very large plane sheet of positive charge is shown. P1 and P2 are two points at distance l and 2l from the charge distribution. If σ is the surface charge density, then the magnitude of electric fields E1 and E2 at P1 and P2 respectively are :
1
E1 = σ/εo, E2 = σ/2 εo
2
E1 = 2 σ/εo, E2 = σ/εo
3
E1 = E2 = σ/2 εo
4
More than one of the above
5
None of the above
