    A rolling body is kept on a plank B. There is sufficient friction between A and B and no friction between B and the inclined plane. Then body :        

    A)     A rolls

    B) A does not experience any friction

    C) A and B has equal acceleration and unequal velocities

    D) A rolls depending upon the angle of inclination \[\theta \]

    Correct Answer: B

    Solution :

    [b] Both the sphere and the plank will slide down with same acceleration g sin\[\theta \].
