  • question_answer
    A particle of mass M is situated at the centre of a spherical shell of same mass and radius a. The gravitational potential at a point situated at \[\frac{a}{2}\] distance from the centre, will be:

    A) \[-\frac{3GM}{a}\]        

    B)        \[-\frac{2GM}{a}\]

    C) \[-\frac{GM}{a}\]          

    D)        \[-\frac{4GM}{a}\]

    Correct Answer: A

    Solution :

    [a] Potential at the given point = Potential at the point due to the shell + Potential due to the particle \[=-\frac{GM}{a}-\frac{2GM}{a}=-\frac{3GM}{a}\]
