A ball is projected from point A with velocity `10 ms^(-1)` perpendicular to the inclined plane as shown in figure. Range of the ball on the inclined plane is

A

`40/3 m`

B

`20/3 m`

C

`12/3 m`

D

`60/3 m`

Text Solution

Verified by Experts

The correct Answer is:
A
`R = u^2/(g cos^2beta) [sin(2alpha+beta)+sin beta]`
`u = 10 m//s, g= 10 m//s^2, beta = 30^@ and alpha = 60^@`.
