Question

plate of mass M is in the shape of a tiangle. Pick the corredt answer(s) from the ollowing The center of mass of the plate can never coincide with the centroid of the plate Even if the density of the plate is non-uniform, the center of mass of the plate always coincides with the centroid of the plate as long as the plate is in the shape of an equilateral triangle uniform It is possible that the center of mass of the plate coincides with the a Regardless of the shape of the plate, the centroid will concide with the center of mass of the plate if the density of the plate is shape of the plate is not an equilateral triangle

Answer 1

Last two options are correct

If density is uniform then center of mass and centroid will definitely coincide .

It is possible that we use discrete mass (non uniform) and we get center of mass at the centroid
