QAIPMT-2010-Ph-2075: NEET 2010 Physics - Class 11 AIPMT-2010-Ph-2075 Solution: Two particles which are initially at rest, move towards each…
Two particles which are initially at rest, move towards each other under the action of their internal attraction. If their speeds are v and 2v at any instant, then the speed of centre of mass of the system will be:
Multiple Choice Options
- A 2v
- B zero
- C 1.5 v
- D v
Step-by-Step Verified Solution
If no external force actson a system of
particles, the centre of mass remains at rest. So,
speed of centre of mass is zero.
