Electrostatics Question 118
Question: If the distance between parallel plates of a capacitor is halved and dielectric constant is doubled then the capacitance [BHU 2001; CBSE PMT 2002]
Options:
A) Decreases two times
B) Increases two times
C) Increases four times
D) Remain the same
Show Answer
Answer:
Correct Answer: C
Solution:
Capacitance with dielectric $ \frac{{}}{{}} $
therefore $ C _{medium}\propto \frac{K}{d} $
