After a perfectly inelastic collision between two identical particles moving with same speed in different directions the speed of the particles becomes half the initial speed. The angle between velocities of the two before collision is -
Text Solution
Verified by ExpertsThe correct answer is:
C
Conservation of linear momentum along x-axis.
mv cos α + mv cos α = 2m(v/2)
⇒ cos α = 
⇒ α = 60 0
∴ Angle between initial velocities = 120 0
