STANDARD Physics Capacitance MCQ Question
Type: MCQ-conceptual-Medium
A parallel plate capacitor having area A and separated by distance d is filled by copper plate of thickness b. The new capacity is
A
ε₀A / (d + b/2)
B
ε₀A / 2d
C
ε₀A / (d - b)
D
2ε₀A / (d + b/2)
Correct Answer
Option A
Detailed Explanation
The new capacitance can be calculated by considering the copper plate as a dielectric slab. The effective separation between the plates is reduced by b/2, leading to the new capacitance formula.
