If CG removed what will happen?

[electrous]

:confused:every body has definite shape and size and also the centre of gravity.so i want to know a certain body have centre of gravity at certain point.
if i remove this portion of body then what will happen to the body? and to the centre of gravity?respectively.
it will be very good for me if you can explain this with help of diagrams.


Thanking you

I'm not sure I understand your question. The center of mass is a mathematical point that is useful for describing some physical properties of a body; it's not a physical part of the body. You can't "remove" the center of mass. (Of course, if you remove any portion of the body, you may affect the location of the center of mass of the remaining material.) Often, the center of mass is not even within the material of the body: For example, the center of mass of a hoop (a donut, say) is in empty space.

If the CG (center of gravity) is removed from a body, the body will lose its balance and stability. The CG is the point at which all the weight of an object is evenly distributed, and it is essential for maintaining equilibrium. Removing the CG means that there will be no point to balance the weight of the object, and it will most likely fall or collapse.

This is similar to removing the legs of a table. The legs provide support and balance, and without them, the table would not be able to stand. Similarly, the CG is like the "leg" of an object, and without it, the object cannot maintain its upright position.

As for the center of gravity itself, if it is removed, there will be no specific point where all the weight is concentrated. This means that the CG will no longer exist, and the body will have a new center of gravity, depending on its new shape and distribution of weight.

I have included a diagram to help illustrate this concept. In the first image, the object has a defined center of gravity at point A. In the second image, if a portion of the object is removed, the center of gravity will shift and be located at point B.

I hope this helps to clarify the concept of center of gravity and its importance in maintaining balance and stability in objects. Thank you for your question, and please let me know if you require further explanation.
