take the mass of 5 kg on the origin and assume that 35 kg is kept on x axis with a distance of 70 cm from origin
the y co ordinates become zero
-----------------------
m1 x1 + m2 x2
X = ------------------------------
m1 + m2
5 (0) +35(70)
------------------
5+ 35
2450/40
=61.25
centre of mass will be at a distance of 61.25 cm from origin
the co ordinates are ( 61.25 , 0)
the y co ordinates become zero
-----------------------
m1 x1 + m2 x2
X = ------------------------------
m1 + m2
5 (0) +35(70)
------------------
5+ 35
2450/40

centre of mass will be at a distance of 61.25 cm from origin
the co ordinates are ( 61.25 , 0)
