MCQ
Two charged thin infinite plane sheets of uniform surface charge density $\sigma_{+}$ and $\sigma_{-}$ where $\left|\sigma_{+}\right|>\left|\sigma_{-}\right|$ intersect at right angle. Which of the following best represents the electric field lines for this system
  • ✓

  • B

  • C

  • D

✓

Answer

Correct option: A.

a
Thin infinite uniformly charged planes produces uniform electric field therefore option $2$ and option $3$ are obviously wrong.

And as positive charge density is bigger in magnitude so its field along $Y$ direction will be bigger than field of negative charge in $X$ direction and this is evident in option $1$ so it is correct.
