Two large plane parallel sheets shown in figure have equal but opposite surface charge densities +σ and -σ. A point charge q placed at points P1, P2 and P3 experiences forces F1, F2 and F3 respectively. Then
Choose the correct answer from the options given below.
Answer & explanation
Correct answer: option 2
At point $p_1$ and $p_3$ field due to both plates are in opposite direction hence force on charges at these points are zero.
At point $p_2$ the field due to both plates are in the same direction hence force will be non zero.
The correct answer is Option (2) → $\vec{F}_1 = 0, \vec{F}_2 \neq 0, \vec{F}_3 = 0$
