JEE MainPhysicsCenter of MassMCQ+4 / −1
This question has statement I{\rm I}I and statement II{\rm I}{\rm I}II. Of the four choices given after the statements, choose the one that best describes the two statements. Statement - I{\rm I}I: A point particle of mass mmm moving with speed υ\upsilonυ collides with stationary point particle of mass M.M.M. If the maximum energy loss possible is given as f(12mv2)f\left( {{1 \over 2}m{v^2}} \right)f(21​mv2), then f=(mM+m).f = \left( {{m \over {M + m}}} \right).f=(M+mm​). Statement -II{\rm II}II: Maximum energy loss occurs when the particles get stuck together as a result of the collision.
  1. A
    Statement - I{\rm I}I is true, Statement -II{\rm II}II is true; Statement -II{\rm II}II is the correct explanation of Statement -I{\rm I}I.
  2. B
    Statement - I{\rm I}I is true, Statement -II{\rm II}II is true; Statement -II{\rm II}II is not the correct explanation of Statement -I{\rm I}I.
  3. C
    Statement - I{\rm I}I is true, Statement -II{\rm II}II is false
  4. D
    Statement - I{\rm I}I is false, Statement -II{\rm II}II true.
