. This question has Statement-I and Statement-II. Of the four choices given after the Statements, choose the one that best describes the two Statements. Statement-I: A point particle of mass m moving with speed v collides with stationary point particle of mass M. If the maximum energy loss possible is given as f(12mυ2)thenf=(mM+m). Statement-II: Maximum energy loss occurs when the particles get stuck together as a result of the collision.
