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^(-1)(2)`

B

`tan^(-1)(4)`

C

`tan^(-1)((2)/(3))`

D

`tan^(-1)(3)`

Text Solution

Verified by Experts

The correct Answer is:
b
Given ,H=R
or `(u^(2)sin^(2)theta)/(2g)=(u^(2)sin2theta)/(g)`
`=(2u^(2)sinthetacostheta)/(g)`
or ` tantheta=4`
`rArrtheta=tan^(-1)(4)`
