C.G implies centre of gravity.
What is meant by the centre of gravity?
The centre of gravity is a theoretical point in the body where the body’s total weight is concentrated. Knowing the centre of gravity is important because it predicts how a moving body would behave when subjected to gravity, and it can also be used to construct static structures like buildings and bridges.
(1) Centre of gravity of the ring – In the Centre of the ring. The centre of gravity of a circular ring is located at the centre of the circle by which the ring is formed.
(2) Centre of gravity of the Rhombus – At the point of intersection of the diagonals. The centre of gravity of a rhombus is situated at the intersection point of the two diagonals of the rhombus.
