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=σεo,E2=σ2εo
  2. E1=2σεo,E2=σεo
  3. E1=E2=σ2εo
  4. E1=E2=σεo

Solution

The electric field due to a large uniformly charged non-conducting sheet is given by, E=σ2εo. It is independent of the distance from the sheet. Therefore,

E1=E2=σ2εo
