four bodies of mass 1kg, 2kg,3kg, and 4 kg are situated at four corners of a square of side 2m, take the origin at the center of square. find m.i. if the system passing through the centre and perpendicular to the plane of square

You probably mean to ask:
"Find the moment of inertia of the system about an axis passing through the center.."
Each mass is R = sqrt2 meters from the center.
I = (1 + 2 + 3 + 4)*R^2 = 20 kg*m^2
