In the previous problem, the distance between the balls when their velocity vectors are perpendicular is

A

`(2(v_+ v_(2))sqrt(v_(1)v_(2)))/(g)`

B

`(v_(1) + v_(2)sqrt(v_(1)v_(2)))/(g)`

C

`(v_(1) + v_(2)sqrt(v_(1)v_(2)))/(g)`

D

`(v_(1) + v_(2)sqrt(v_(1)v_(2)))/(2 g)`

Text Solution

Verified by Experts

The correct Answer is:
C
`x_(1) = v_(1) t, x_(2) = v_(2) t`
Distance between balls `d = (v_(1) + v_(2))t`
`= ((v_(1) + v_(2))sqrt(v_(1)v_(2)))/(g)`
