Two particles are intially at a separation of d to each other. They move with constant velocirties with `5m//s` and `3m//s` respectively in horizontal plane. Their velocities makes an angle `60^(@)` with each other. If after 2 seconds, they collide. Then value of d is:

A

`2sqrt(19)m`

B

`8m`

C

`2m`

D

`32m`

Text Solution

Verified by Experts

The correct Answer is:
A
Two particlesw …………….. a

`cos 60^(@) = (10^(2)+6^(2)-d^(2))/(2xx10xx6)`
`(1)/(2) = (100+36-d^(2))/(120)`
`d = 2sqrt(19)`
