    A disc whose radius R is revolving around its geometrical axis if we increase  radius to 2R and constant speed then the centripetal force will be:

    A)  half                      

    B)         double

    C)         equal                   

    D)         one fourth

    Correct Answer: C

    Solution :

    Centripetal force depends on the radius of circular path, not on the radius of the body. On changing radius of body, centripetal force will remain same.
