Electrostatics Question 151
Question: The capacity of an air condenser is 2.0 mF. If a medium is placed between its plates. The capacity becomes 12 mF. The dielectric constant of the medium will be [Pb. PMT 2003]
Options:
A) 5
B) 4
C) 3
D) 6
Show Answer
Answer:
Correct Answer: D
Solution:
Dielectric constant of medium $ K=\frac{\text{Capacity of condenser with medium}}{\text{Capacity of condenser}}=\frac{12}{2.0}=6 $
