Question

What is the center of mass of rectangular plate?

Answer 1

meeting points of diagonal

Answer 2

Answer:

If an object having uniform thickness and density , then the meeting points of diagonal gives the center of gravity.

That is If you draw the diagonals and the point where the two diagonals intersect gives you the geometric center ( which is also called the center of the rectangle ) which is termed as the center of mass for a uniform rectangular shaped lamina.

The center of mass need not be at the geometric center.

If the rectangle has uneven mass distribution then the center of mass will shift towards the region where there is more mass.
