A particle is projected up with a velocity of `v_(0)=10m//s` at an angle of `theta_(0)=60^(@)` with horizontal onto an inclined plane. The angle of inclination of the plane is `30^(@)`. The time of flight of the particle till it strikes the plane is (take `g=10ms^(-2)`)

A

`1s`

B

`1//2s`

C

`2/(sqrt(3))s`

D

`1/(2sqrt(3))s`

Text Solution

Verified by Experts

The correct Answer is:
c
`T=(2u_(y))/(a_(y))=(2v_(0)sin 30^(@))/(g cos 30^(@))=2/(sqrt3)s`
