    What is the minimum velocity with which a body of mass m must enter a vertical loop of radius R so that it can complete the loop?                                                                                                                                       

    A)  \[\sqrt{gR}\]                    

    B)  \[\sqrt{2gR}\]

    C)   \[\sqrt{3gR}\]                 

    D)  \[\sqrt{5gR}\]

    Correct Answer: D

    Solution :

    When minimum speed of body is \[\sqrt{5gR},\] then no matter from where it enters the loop, it will complete full vertical loop.
