In the figure, a very large plane sheet of positive charge is shown. P1and 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:(A) E1 = σ/ε0, E2 = σ/2ε0(B) E1 = 2σ/ε0, E2 = σ/ε0(C) E1 = E2 = σ/2ε0(D) E1 = E2 = σ/ε0 |

Answer» Correct option is (C) E1 = E2 = σ/2ε0 As the sheet is very large \(\vec E\) is independent of distance from it. Thus E1 = E2 = \(\frac{\sigma}{2\varepsilon_0}\) |
