Question:

Let $\mathcal{D}$ be the domain in Figure 22. Assume that $\mathcal{D}$ is symmetric with respect to the $y$-axis; that is, both $g_{1}(x)$ and $g_{2}(x)$ are even functions.

(a) Prove that the centroid lies on the $y$-axis-that is, that $\bar{x}=0$.

(b) Show that if the mass density satisfies $\delta(-x, y)=\delta(x, y)$, then $M_{y}=0$ and $x_{\mathrm{CM}}=0$.
