How do we know whether a body is in stable or unstable state due to position of its centre of gravity?

Roughly speaking, a body will be stable if its center of gravity, projected downward, is inside the surface on which it rests.

What is an example of unstable equilibrium in sports?
unstable equilibriu is whenthe centre of gravity of a body lies above the point of suspension and supports.
How center of gravity determines whether the objects is at rest or in motion.?
The centre of gravity does not, by itself, determine whether an object is at rest or in motion. The location of the centre of gravity, relative to where the object is supported, can contribute one of many forces that can act on the object. And it is is the [vector] sum of these forces which determines whether the object remains at rest or in uniform motion.
Meter rod balanced on a wedge is in which state of equilibrium?
A metre rod will be in the state of neutral equilibrium.This is because its centre of gravity remains same whether its raised or not.It has a fixed centre of gravity.
What is the center of gravity for a lamina?
If the lamina is in two dimensions (i.e. not curled round into a third dimension) then the centre of gravity will be somewhere within the flat shape. The position of the centre of gravity will depend on the distribution of mass across the lamina. If the lamina is curled round into a third dimension then the centre of gravity will be somewhere within the volume enclosed, fully or partially, by the lamina; this may or may not be on the lamina.
How can you locate the center of gravity?
Usually the centre of gravity is at the centre of the object, scaling from both sides OR centre of mass where the object is stable when holding it up on a pin point

Does it do more then the back?
It is more difficult to lean backwards because the centre of gravity of the body lower and unstable equilibrium establishes and difficult to come back to original position. SLPS director
Does the position of the Metacentre depend on the position of the centre of gravity?
yes. from curtin student
What is unstable equilibrium?
When a body is in unstable equilibrium, on slight displacement the centre of gravity of the body will be lowered. If the line of action of its weight lies outside the base area of the body, it will topple. Objects that have high centres of gravity, a small base area, or are top-heavy are more likely to be in unstable equilibrium. Stability can be increased by lowering the centre of gravity and/or increasing the area and/or the weight of the base.
Why persons in a small boat are not allowed to stand?
It raises the boat's centre of gravity which will in turn make it more unstable.
Why not the car engine kept above body?
Because the height of the engine would raise the cars centre of gravity - making it unstable !

Why a men bow himself while carrying heavy lod on his back?
Every object on the Earth is governed by a force called Gravity. But regardless to the shape of the object, every oject has a 'centre of Gravity'. To, attain the position of stability the centre of gravity and the centre of mass of that object should be on same vertical line (perpendicular to earth). So, when man lift the heavy weight it total mass increased and and the centre of mass deviates from the centre of gravity of that man (man+ weight), so to maintain the stability man bow down to bring back its centre of mass with its centre of gravity. and in this way he can walk/stand with the load, otherwise we will fall back with its load.
Does the centre of gravity change on moon?
As compared to Earth, you mean? If an object doesn't change its shape, the center of mass doesn't depend on gravity - and the center of gravity hardly does so.
Why is suns gravity only in the perimeter?
It isn't. Gravity can be viewed as emanating from the centre of a body with mass. As the distance increases from the centre then the gravity decreases.
