Alokik Gupta asked • 23 hours agoA mass M collides elastically with a stationary mass m. If M < m, then it is possible for M to bounce directly backwards. However, if M > m, then there is a maximum angle of deflection of M. Then angle is- a)sin φ = M/m
- b)sin φ = m/M
- c)tan φ = M/m
- d)tan φ = m/M
Correct answer is option 'B'. Can you explain this answer?
