  • question_answer
    An artificial satellite moving in a circular orbit around the earth has a total (kinetic + potential) energy \[{{E}_{0}}.\] Its potential energy is

    A) \[-{{E}_{0}}\]              

    B)        \[1.5{{E}_{0}}\]

    C) \[2{{E}_{0}}\]             

    D)        \[{{E}_{0}}\]

    Correct Answer: C

    Solution :

    [c] \[P.E.=2T.E.\] \[\Rightarrow \]\[P.E.=2{{E}_{0}}\] In case of circular motion of satellite around the earth / planets revolving around sun/ electrons revolving in circular orbit P.E. = 2 T.E. and |K.E.|=|T.E.|].
