Two bullets are fired at an angle of `theta` and ( 90 - `theta` ) to the horizontal with same speed. The ratio of their times of flight is

A

`1:1`

B

`1:tantheta`

C

`tantheta:1`

D

`tan^(2)theta:1`

Text Solution

Verified by Experts

The correct Answer is:
A
Time of flight `t_(f)=(2xsintheta)/(9)`
`t_(f)propsintheta`
`:.(t_(f_(1)))/(t_(f_(2)))=(sintheta)/(sin(90-theta))=(sintheta)/(costheta)=tantheta,t_(f_(1)):t_(f_(2))=tantheta:1`
