NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Medium-Class 12
Consider a parallel plate capacitor with plates labeled A and B. If the surface charge density on plate A is σ and on plate B is −σ, what is the electric field between the plates?
A
E = σ / ε₀
B
E = 2σ / ε₀
C
E = σ / 2ε₀
D
E = 0
Correct Answer
Option A
Detailed Explanation
The electric field between the plates of a parallel plate capacitor is given by E = σ / ε₀, where σ is the surface charge density and ε₀ is the permittivity of free space.
