  • question_answer
    A solid sphere of radius R is placed on a smooth horizontal surface. A horizontal force F is applied at height h from the lowest point. For the maximum acceleration of the centre of mass,

    A) \[h=R\] 

    B) \[h=2R\]

    C) \[h=0\]

    D) The acceleration will be same whatever h maybe

    Correct Answer: D

    Solution :

    [d] As friction is absent at the point of contact, Force Accelerati on \[=\frac{Force}{Mass}\] It is independent of h
