Masses 
are placed at the corners 
respectively of a square 
of diagonal 
. The distance of centre of mass from 
will be
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
Let corner A of square ABCD is at the origin and the mass 8 kg is placed at this corner (given in problem) Diagonal of square 
⇒ ⇒ 
Let 
are the position vectors of respective masses
, 
, 
, 
From the formula of centre of mass
co-ordinates of centre of mass 
and co-ordination of the corner 
From the formula of distance between two points 
and 
distance 
= 
= 
=
