QNEET-2023-Ph-347: NEET 2023 Physics - Class 11 NEET-2023-Ph-347 Solution: Two particles A and B initially at rest move towards each other …
Two particles A and B initially at rest move towards each other under mutual force of attraction. At an instance when the speed of A is v and speed of B is 3v the speed of centre of mass is: 2v zero v 4v
Multiple Choice Options
- A 2v
- B zero
- C v
- D 4v
Step-by-Step Verified Solution
Final velocity of centre of mass = Initial velocity of centre of mass = 0 because net external force on system is zero.
