    The given graph represents

    A) the velocity of the body is variable

    B) the velocity of the body is constant

    C) the mass of the body is constant

    D) None of the above

    Correct Answer: B

    Solution :

    [b] As, we know, momentum (p) = mass (m) \[\times \] velocity Thus, the slope of momentum versus mass graph shows velocity of body. Also, the given slope is a straight line. So, the velocity is constant.
