  • question_answer
    A sphere collides with another sphere of identical mass. After collision, the two spheres move. The collision is inelastic. Then the angle between the directions of the two spheres is                    [KCET 1994]

    A)          \[90{}^\circ \]             

    B)  \[0{}^\circ \]

    C)          \[45{}^\circ \]             

    D)          Different from\[90{}^\circ \]

    Correct Answer: D

    Solution :

                                      Angle will be \[90{}^\circ \]if collision is perfectly elastic
