Four particle of masses m, 2m , 3m and 4m are arranged at the corners of a parallelogram with each side equal to ‘ a ‘ and one of the angle between two adjacent sides is 60°. The parallelogram lies in the x-y plane with mass ‘ m ‘ at the origin and ‘ 4m ‘ on the x-axis. The centre of mass of the arrangement will be located at
