A particle is projected up an inclined plane with initial speed v=20m/s at an angle theta=30° with plane .The component of its velocity perpendicular to plane when it strikes the plane is
10√3m/s
15m/s
10m/s
20√3m/s
0m/s
5m/s
5√3m/s

Component of velocity perpendicular to plane remains the same (in opposite direction). I.e., usin theta = 20 sin30° = 10m/s
