Four particles, each of mass `1kg` are placed at the corners of a square of side `1m` in the `XY` plane. If the point of intersecting of the diagonals of the square is taken as the origin, the co-ordinates fo the centre of mass are

Four particles, each of mass 1kg, are placed at the corners of a square of side one meter in the X - Y plane. If the point of intersection of the diagonals of the square is taken as the origin, the coordinates of the centre of mass are

Four particle, each of mass m, are placed at corners of a square of side a in the x-y plane. If the origin of the co-ordinate system is taken at the point fo intersection of the diagonals of the square, the co-ordinates of the centre of mass of the system are:

Four particles of masses 1kg ,2kg, 3kg and 4kg are placed at the corners of a square of side 2m in the x-y plane If the origin of the co-ordinate system is taken at the mass of 1kg, the (x,y) co-ordinates of the enter of mass expressed in metre are :
