Three point masses of 1 kg, 2kg and 3 kg lie at (0, 0), (1, 2), (3, -1), respectively. Calculate the coordinates of the centre of mass of the system.

Three point masses of 1 kg, 2kg and 3 kg lie at (0, 0), (1, 2), (3, -1

1.	Three point masses of 1 kg, 2kg and 3 kg lie at (0, 0), (1, 2), (3, -1), respectively. Calculate the coordinates of the centre of mass of the system.
Answer» SOLUTION :`x =(m_(1)x_(1) + m_(2)x_(2) + m_(3)x_(3))//m_(1)vec(a_(1)) + m_(2)vec(a_(2)) = m_(1)VECA - m_(2)veca = (m_(1) - m_(2))(m_(1)-m_(2)) vecg//m_(1) + m_(2) veca_("CM") = (m_(1)-m_(2))^(2) vecg//(m_(1) + m_(2))^(2)`
