  • question_answer
    A satellite moves around the earth in a circular orbit of radius r with speed v. If the mass of the satellite is M, its total energy is                     [MP PMT 2001]

    A)             \[-\frac{1}{2}M{{v}^{2}}\]

    B)               \[\frac{1}{2}M{{v}^{2}}\]

    C)             \[\frac{3}{2}M{{v}^{2}}\] 

    D)             \[M{{v}^{2}}\]

    Correct Answer: A

    Solution :

        Total energy = ? (kinetic energy) = \[-\frac{1}{2}M{{v}^{2}}\]
