In the adjacent diagram, objects 1 and 2 each have mass m while objects 3 and 4 each have mass 2m. Note four lines A, B, C and D. The center of mass of the system is most likely to be at the intersection of lines :

Four rods AB, BC, CD and DA have mass m,2m,3m and 4m respectively. The center of mass of all the four rods

Four rods AB, BC, CD and DA have mass m,2m,3m and 4m respectively. The center of mass of all the four rods

Four masses m, 2 m, 3 m and 4 m are connected by a rod of negligible mass. The moment of inertia of the system about the axis AB is

Two objects of masses 1kg and 2kg separated by a distance of 1.2m are rotating about their centre of mass. Find the moment of inertia of the system

Assertion: An object of mass m_1 and another of mass m_2(m_2gtm_1) are released from certain distance. The objects move towards each other under the gravitational force between them. In this motion, centre of mass of their system will continuously move towards the heavier mass m_2 . Reason: In a system of a heavier and a lighter mass, centre of mass lies closer to the heavier mass.
