Option (D) is the correct answer.
Here is the explanation :
Initial momentum of the particles = mv +0 = mv
which is along x-axis.
After collision the net momentum of the system should also be equal to mv and along x-axis only
Thus,
the 2nd particle should have two velocities, one equal to v/(root 3) opposite to the velocity of first particle after collision
And other velocity equal to v along x axis
Thus net speed of 2nd particle after collision is equal to magnitude of [ v/(root 3)j + v i]
Which is equal to 2v/(root3)
