b$)$ The Shape below is composed two different materials with equal volume but different densities so the masses are different $(\backslash (\backslash$mathbf$\{$m $1>$ m $2\}\backslash )).$ Which points $(\backslash ($ A$,$ B $\backslash ),$ or $\backslash ($ C $\backslash ))$ could possibly be the Centroid, and the Center of Mass of the shape composed of the both the materials? Justify your answer $(5$ points$)$

Centroid:

A

B

C

Center of Mass:

$($A$)$

$\backslash ($ B $\backslash )$

C
