NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Hard-Class 12
Consider a parallel plate capacitor with an air gap between its plates as shown in a diagram. If the distance between the plates is reduced while keeping the charge on the plates constant, what effect does this have on the electric field between the plates?
A
The electric field remains constant.
B
The electric field increases.
C
The electric field decreases.
D
The electric field becomes zero.
Correct Answer
Option A
Detailed Explanation
According to the NCERT context, the electric field between the plates of a parallel plate capacitor is given by E = σ/ε₀, which is independent of the distance between the plates when the charge and plate area are constant.
