The center of mass of three particles of mass 
and 3 kg is at 
with reference to a fixed coordinate system. Where should a fourth particle of mass 4 kg be placed, so that the centre of mass of the system of all particles shifts to a point 
?
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
Coordinates of initial center of mass,
When center of mass shifts to 
… (ii)
Solving eq. (i) and (ii), we get
Similarly, 
The fourth particle must be placed at the point ( 
).
