A gun fires two bullets 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. Hence
`h/(h')=(u^(2) sin^(2)60^(@))/(2g)xx(2g)/(u^(2) sin^(2)30^(@))=(sin^(2)60^(@))/(sin^(2)30^(@))=3/1`
