Consider elastic collision of a particle of mass m moving with a velocity u with another particle of the same mass at rest. After the collision the projectile and the struck particle move in directions making angles $e_1$ and $e_0^2$ respectively with the initial direction of motion. The sum of the angles. $\theta_1 + \theta_2,$ is
Text Solution
Verified by ExpertsThe correct answer is:
B
If the masses are equal and target is at rest and after collision both masses moves in different direction. Then angle between direction of velocity will be 90°, if collision is elastic.
