Show how you would check the accuracy of your result by, ( i) a geometrical construction and measurement and ( ii ) by a second simple experiment where should the centre of gravity be located ? ( b ) Explain how the position of the centre of gravity of a body determines whether it is in stable or unstable equilibrium, illustrate your answer by diagrams
Rotational Equilibrium And Rotational Dynamics
In physics, the state of balance between the forces and the dynamics of motion is called the equilibrium state. The balance between various forces acting on a system in a rotational motion is called rotational equilibrium or rotational dynamics.
Equilibrium of Forces
The tension created on one body during push or pull is known as force.

( i) a geometrical construction and measurement and
( ii ) by a second simple experiment where should the centre of gravity be located ?
( b ) Explain how the position of the centre of gravity of a body determines whether it is in stable or unstable equilibrium, illustrate your answer by diagrams
(i) we can check accuracy by simple observation of geometrical construction and by measuring dimension's with instrument like vernier calliper , micrometer etc for more accuracy .
(ii) The Centre of gravity is a theoretical point in the body where the body’s total weight is thought to be concentrated. It can lie outside or inside the object .For simple shaped object center of gravity can can be located as follow .
When we balance an object with the help of a string or an edge, the point at which the object balances is the centre of gravity of that object.
