The angle of projection at which the horizontal range and maximum height of projectile are equal is

A

`45^(@)`

B

`theta = tan^(-1) (0.25)`

C

`theta = tan^(-1)4` or `(theta = 76^(@))`

D

`60^(@)`

Text Solution

Verified by Experts

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