Two particles P and Q simultaneously sta...

Two particles P and Q simultaneously start moving from point A with velocities `15 m//s` and `20 m//s` respectively. The two particles move with acceleration equal in magnitude but opposite in direction. When P overtakes Q at point B then its velocity is `30 m//s`, the velocity of Q at point B will be

A

30 m/s

B

5 m/s

C

10 m/s

D

15 m/s

Text Solution

Verified by Experts

The correct Answer is:
B
`v_("rel") = at`
For P: `30 = 15 + at`
For Q: `y = 20 - at`
