Which one of the following statement does not hold good when two balls of masses ${m_1}$ and ${m_2}$ undergo elastic collision
- A
When ${m_1} < < {m_2}$ and ${m_2}$ at rest, there will be maximum transfer of momentum
- B
When ${m_1} > > {m_2}$ and ${m_2}$ at rest, after collision the ball of mass ${m_2}$ moves with four times the velocity of ${m_1}$
- C
When collision is oblique and ${m_2}$ at rest with ${m_1} = {m_2}$, after collision the balls move in opposite directions
- D
$(b)$ or $(c)$ both
