    When air is replaced by a dielectric medium of constant K, the maximum force of attraction between two charges separated by a distance

    A) increases K times

    B) remains unchanged

    C) decreases K times

    D) increases 2K times.

    Correct Answer: C

    Solution :

    As \[{{F}_{m}}=\frac{{{F}_{o}}}{K}\] \[\therefore \]The maximum force decreases by K times.
