A particle of mass m moving towards west...

A particle of mass m moving towards west with speed v collides with another particle of mass m movies towards south. If two particles st ich t o each other the speed of the new particle of mass 2 m will be

A

v

B

`v//2`

C

`v/(sqrt2)`

D

`vsqrt(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
Let `W - E` is x-axis `S - N` is Y - axis & `bar(v)` be final velocity vector.
`implies 2 m barv = m v hat I + m v hatj implies barv = v/2 (hati + hatj)`
`implies |barv| = v/(sqrt2)`
