A) \[\frac{{{m}_{1}}+{{m}_{2}}}{{{m}_{1}}+{{m}_{2}}}\cdot T\]
B) \[\frac{{{m}_{1}}}{{{m}_{1}}+{{m}_{2}}}\cdot T\]
C) \[\frac{{{m}_{2}}}{{{m}_{1}}+{{m}_{2}}}\cdot T\]
D) zero
Correct Answer: D
Solution :
As system is released at \[t=0,\]momentum of system at any instant t is \[p(t)={{M}_{\text{system}}}\times {{v}_{CM}}={{p}_{\text{system}}}(t=0)=0\] \[\therefore \]\[{{v}_{CM}}=0\] So, centre of mass of system is always at rest and is not oscillating.You need to login to perform this action.
