oblique collision

JEE Main 2015 Preparation › Mechanics questions › oblique collision

A particle of mass m collides oblically with another particle of mass 2m initially at rest. Both the particles have same diameter at the instant of collision velocity of 1st particle is making an angle of pie/3 with the line joining the centres of the particles. If velocity of 1st particle before collision is 2metre/sec. Find its velocity after collision. The collision is perfectly elastic.

Sorry, there is some mistake. 2pie/3-tan inverse3âˆš3 is angle of deflection. Its answer is 2âˆš7/3 m per sec.
