QNEET-2022-Ph-543: NEET 2022 Physics - Class 12 NEET-2022-Ph-543 Solution: The distance between the two plates of a parallel plate…
The distance between the two plates of a parallel plate capacitor is doubled and the area of each plate is halved. If C is its initial capacitance its final capacitance is equal to 4C 2C C/2 C/4
Multiple Choice Options
- A 4 C _
- B 2C
- C 2 C _
- D 4C
Step-by-Step Verified Solution
For a capacitor of area A and distance between the plates as d, the capacitance (C) is
C = A _ 0 d
On doubling the distance and reducing area to half
C 1 = A 2 _ 0 2 d
_ C 1 = A _ 0 4 d
_ C 1 = C 4
