Vedclass · Accepted Answer

When the collision is oblique and $m_2$ is at rest with $m_1 = m_2$,after collision the balls move in opposite directions.

Vedclass · Answer

(D) In an elastic collision between two bodies of equal mass $(m_1 = m_2)$ where one is initially at rest,if the collision is oblique,the two bodies move at an angle of $90^{\circ}$ to each other,not in opposite directions. Thus,statement $(d)$ is incorrect.For $(a)$: When $m_1 \ll m_2$,the momentum transfer is indeed maximum.For $(b)$: If $m_1 \gg m_2$,the velocity of the second ball becomes $v_2 \approx 2u_1$,which is a standard result,but the specific claim in $(b)$ is generally considered a distractor or incorrect depending on the mass ratio context,however,$(d)$ is physically impossible for oblique collisions.For $(c)$: When $m_1 = m_2$ and $m_2$ is at rest,the first ball comes to rest and the second moves with the initial velocity of the first,resulting in $100\%$ transfer of $K.E$.

Which one of the following statements does not hold good when two balls of masses $m_1$ and $m_2$ undergo elastic collision?
