Electric Flux & Gauss's Law
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 is the surface charge density, then the magnitude of electric fields E1 and E2 at P1 and P2 respectively are:

Show answer and solution
Answer: (c)
- Infinite sheet: , independent of distance.
- So .
- So the answer is (c).
