In the above figure, a small weight is placed at 2 cm (0.02 m) from the center of the rectangular prism. Let's call the mass of this small weight (M1) and the mass of the entire body including the small weight (M) Given the dimensions above, I want to know how to calculate the height of center of gravity from the base of the prism. I know that we have to take moments but I am a little confused. If anyone can help clarify how this can be done, it would be very helpful.
P.S - Just in case anyone is wondering, COG is not at the center of the object i.e it is not H/2 (Yes I did think that at first). The reason for this, the small weight has a certain mass and placing the weight on the object will alter its center of gravity. With increasing weight the height of center of gravity should increase from the base.
P.P.S. - The prism is hollow on top and not fully enclosed. And the horizontal black line which is parallel to W represents a rod on which the small weight was placed
So if anyone knows how to get the center of gravity by taking moments, please explain it to me
