A unifrom disc A of radius 2m is cut as shown in the image. The cut out is also a disc of radius 1m. Find the distance of the two center of gravity before and after the paper disc is cut.
The Attempt at a Solution
Mass of the disc is proportional to its area.
so mass of disc A=2^2pi=4pi units
mass of disc being cut out=1^2pi=pi units
Let x be the distance between the two centers of gravity.
This question is quite difficult for me. I don't have much confidence on my answer.:tongue2: May anyone try it?
