Three particles of the same mass lie in the x-y plane. The (x, y) coordinates of their positions are (1, 1), (2, 2) and (3, 3) respectively. The (x, y) co-ordinates of the centre of mass are:

Answer»

(1, 2)
(2, 2)
(4, 2)
(6, 6)

Solution :The x COMPONENT of centre of MASS is
`x=(mxx1+mxx2+mxx3)/(m+m+m)=(1)/(3)(1+2+3)=2`
Similarly,
`y=(mxx1+mxx2+mxx3)/(3M)=(1)/(3)(1+2+3)=2`
