A gun fires two bulets at `60^(@) and 30^(@)` with the horizontal The bullets strike at some horizontal distance. The ratio of maximum height for the two bullet is

A

`2:1`

B

`3:1`

C

`4:1`

D

`1:1`

Text Solution

Verified by Experts

The correct Answer is:
B
The bullets are fired at the same initial speed
`H/(H.)=(u^2 sin^2 60^@)/(2g) xx (2g)/(u^2 sin^2 30^@) = (sin^2 60^@)/(sin^2 30^@)=(sqrt3//2)^2/(1//2)^2=3/1`
