  • question_answer
    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]

    A)                    5

    B)                                      4

    C)                    3                                        

    D)            6

    Correct Answer: D

    Solution :

               Dielectric constant of medium \[K=\frac{\text{Capacity of condenser with medium}}{\text{Capacity of condenser}}=\frac{12}{2.0}=6\]
