Two stones are projected from the top of...

Two stones are projected from the top of a tower in opposite direction, with the same velocity `V` but as `30^(@)` and `60^(@)` with horizontal respectively.The relative velocity of first stone relative to second stone is

A

`2v`

B

`sqrt2v`

C

`(2V)/sqrt3`

D

`V/sqrt3`

Text Solution

Verified by Experts

The correct Answer is:
B
`vecV_(1)=Vcos30hati+Vsin30hatj`
`vecV_(2)=-Vcos60hati+Vsin60hatj`
`vecV_(1)=Vcos30hati+Vsin30hatj`
`vecV_(12) =vecV_(1)-vecV_(2)`
