  • question_answer
    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 :

    (c) decreases K times As \[{{F}_{m}}=\frac{{{F}_{0}}}{K}\] \[\therefore \] The maximum force decreases by K times.
