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(1/2 mv^2) then f = (m/(m+M)). Statement - II: Maximum energy loss occurs when the particles get stuck together as a result of the collision.

  1. Statement-I is true, Statement-II is false.
  2. Statement-I is false, Statement-II is true.
  3. Statement-I is true, Statement-II is true.
  4. Statement-I is true, Statement-II is true, Statement-II is not a correct explanation of Statement-I.

Correct answer: Statement-I is false, Statement-II is true.

Solution

Statement-I incorrectly describes the maximum energy loss in a collision, as it does not accurately reflect the relationship between the masses and energy loss. Statement-II is true because maximum energy loss indeed occurs when the particles stick together, which is a valid scenario in inelastic collisions.
