This question has statement $1$ and statement $2$ . Of the four choices given after the statements, choose the one that best describes the two statements.
Statement $- 1$: A point particle of mass m moving with speed $u$ collides with stationary point particle of mass $M$. If the maximum energy loss possible is given as $f$ $\left( {\frac{1}{2}m{v^2}} \right)$ then $ f = \left( {\frac{m}{{M + m}}} \right)$
→Statement $- 1$: A point particle of mass m moving with speed $u$ collides with stationary point particle of mass $M$. If the maximum energy loss possible is given as $f$ $\left( {\frac{1}{2}m{v^2}} \right)$ then $ f = \left( {\frac{m}{{M + m}}} \right)$
Statement $-2$: Maximum energy loss occurs when the particles get stuck together as a result of the collision.

→A uniform body of mass $M$ radius $R$ has a small mass $m$ attached at edge as shown in the figure. The system is placed on a perfectly rough horizontal surface such that mass $m$ is at the same horizontal level as the centre of body. It is assumed that there is no slipping at point $A$. If $I_A$ is the moment of the inertia of combined system about point of contact $A$ then the normal reaction at point $A$ just after the system is released from rest is ........ $N$.
