Four balls `A, B, C` and `D` are projected with equal velocities having angles of projection `15^(@)`, `30^(@)`, `45^(@)` and `60^(@)` with the horizontal, respectively. The ball having the smallest range is

A

`A`

B

`B`

C

`C`

D

`D`

Text Solution

Verified by Experts

The correct Answer is:
A
`R_(A) alpha sin 30^(@), R_(B) alpha sin 60^(@)`
`R_( C) alpha sin 90^(@), R_(D) alpha(sin 120^(@) = sin 60^(@))`
`R_(A)` is the smallest.
