    A body of mass m rises to a height h = \[-3Mg\frac{d}{4}\] from the earths surface where R is earths radius. If g is acceleration due to gravity at the earths surface, the increase in potential energy will be

    A)  mgh                                     

    B) \[l\] mgh             

    C)                        \[2l\] mgh         

    D)        \[\frac{l}{2}\] mgh

    Correct Answer: C

    Solution :

    Increase in gravitational potential energy \[\frac{8}{3}V\] \[l\] \[5\sqrt{3}\times {{10}^{-7}}N-m\] \[5\sqrt{3}\times {{10}^{-10}}N-m\] \[\frac{\sqrt{3}}{5}\times {{10}^{-7}}N-m\]        [\[\Omega \]\[1\mu F\]]
