A system of two particles is having masses 
and 
. If the particle of mass 
is pushed towards the centre of mass of particles through a distance 
, by what distance the particle of mass 
should be moved, so as to keep the centre of mass of particles at the original position?
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Initial position of centre of mass;
Here, 
and 
are the distances of mass 
and 
from centre of mass respectively.
In second case,
Here, 
and 
are the displacement of mass 
and 
respectively.
