A gun fires two bullets with same velocity at 60^(@) and 30^(@) with horizontal. The bullets strike at the same horizontal distance. The ratio of maximum height for the two bullets is in the ratio of

Answer»

`1:2`
`3:1`
`2:1`
`1:3`

SOLUTION :Max height attained `h_(max)=(u^(2)sin^(2)theta)/(2g)`
`:.h_(max)propsin^(2)theta` i.e., `h_(max)PROP(1-cos2theta)/(2)`
`(h_(max1))/(h_(max2))=(3//2)/(1//2)=3`
