In the figure, the `L-`shaped shaded piece is cut from a metal plate of uniform thickness. The point that corresponding to the center of mass of the `L-`shapped piece is `:-`

The distance of the centre of mass of T-shaped uniform plate from O is :

The distance of the centre of mass of T-shaped uniform plate from O is :

A uniform piece of metal sheet is cut in the form as shown in the figure. Locate the centre of mass of the piece.

The figure shows a metallic plate of uniform thickness and density. The value of l in terms of L so that the centre of mass of the system lies at the interface of the triangular and rectangular portion is
