    The figure given below shows a planet in elliptical orbit around the sun\[S\]. At what position will the kinetic energy of the planet be maximum?

    A) \[{{P}_{1}}\]                             

    B) \[{{P}_{4}}\]

    C) \[{{P}_{3}}\]               

    D)        \[{{P}_{2}}\]

    Correct Answer: A

    Solution :

     In the figure shown, at point\[P\], the kinetic energy of the planet is maximum as it has the least value of radius vector with greater forces of gravitational attraction.
