Three identical spheres each of diameter 
are kept on a horizontal surface such that each sphere touches the other two spheres. If one of the sphere is removed, then the shift in the position of the centre of mass of the system is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
The coordinates of centre of mass of the spheres is given by
As the spheres are idertical,
Similarly,
So, the centre of mass, 
If one sphere is removed (say C), then
So, 
Hence, the centre of mass shifted by 
in 
direction. The correct option is .
