A particle is prjected up an inclined with initial speed `v=20m//s` at an angle `theta=30^(@)` with the plane. The component of its velocity perpendicular to the plane when it strikes the plane is:

A

`10sqrt(3) m//s`

B

`10 m//s`

C

`5sqrt(3) m//s`

D

data is insufficient

Text Solution

Verified by Experts

The correct Answer is:
b
Component of velocity `bot` to plane remains the same (in opposite direction).
`u sin theta=20sin 30^(@)=10m//s`
