At what angle to the horizontal should an object be projected so that the maximum height reached is equal to the horizontal range.

A

`tan theta=2`

B

`tan theta=4`

C

`tan theta=2//3`

D

`theta=3`

Text Solution

Verified by Experts

The correct Answer is:
b
H=R
`(u^(2)sin^(2)theta)/(2g)=(u^(2)sin 2 theta)/(g)`
`(1)/(2)sin^(2)theta=(2 sin thetacos theta)`
`tan theta=4`
