Question
What is the electric field in the region between two large parallel conducting plates with equal and opposite surface charge densities ±σ?
Correct Answer
Option B is the correct answer.
Detailed Explanation
The fields from the two oppositely charged plates add between the plates: E = σ/(2ε₀) + σ/(2ε₀) = σ/ε₀. Outside, they cancel.
Hint
Fields reinforce between plates.
