u=Velocity of particle
v=Velocity of wedge
Horizontal range of projectile:
R=u2sin2θ/g
=(10√3)²sin120/g

=(103√)2/g×3/√2
=150√3g
Time taken by the particle to strike the wedge:
t=R/v  =150√3/g×110√3
=15/10
=1.5 s  ≈ 2 s
Thus,
Time taken by the particle to strike the wedge is 2 second

The final answer is 2 sec but the process is incorrect..its a problem of relative motion and also the angle of inclination of the wedge needs some consideration. So if anyone can find another explanation do share it!
Thanks!
