Center of MassEasy
Question
Two partiicles A and B initially at rest, move twowards each other by mutual force of attraction. At the instant when the speed of A is v and speed of B is 2v, the speed of the centre of mass of the system is
Options
A.3 v
B.v
C.1.5 v
D.zero
Solution
Net force on centre off mass is zero. Therefore, centre of mass always remains at rest.
