Question

A body of mass m collision obliquely with another identical body at rest. Assuming collision to be elastic. The colliding bodies will move at an angle of :

• A. 60${}^o$ to one another
• B. 90${}^o$ to one another
• C. 120${}^o$ to one another
• D. 30${}^o$ to one another

Answer 1

Answer: (B)

90${}^o$ to one another

In oblique elastic collision the momentum is conserved in X and Y directions separately, also kinetic energy is also conserved. If colliding masses are same then in such collision equal masses will fly away right angles to each other.
