Two large plane parallel sheets with equal but opposite surface charge densities \(+\sigma\) and \(-\sigma\). A point charge q placed at points P1, P2, and P3 experiences forces F1, F2, and F3 respectively. Then :
- A \(F 1=0, F 2=0, F 3=0\)
- B \(F 1=0, F 2 \neq 0, F 3=0\)
- C \(F 1 \neq 0, F 2 \neq 0, F 3 \neq 0\)
- D \(F 1=0, F 3 \neq 0, F 2=0\)
Answer & Solution
Correct Answer
(B) \(F 1=0, F 2 \neq 0, F 3=0\)
Step-by-step Solution
Detailed explanation
\(E_{P1} = \frac{\sigma}{2\epsilon_0} - \frac{\sigma}{2\epsilon_0} = 0\) \(F_1 = qE_{P1} = 0\) \(E_{P2} = \frac{\sigma}{2\epsilon_0} + \frac{\sigma}{2\epsilon_0} = \frac{\sigma}{\epsilon_0}\) \(F_2 = qE_{P2} = q\frac{\sigma}{\epsilon_0} \neq 0\)…
