Formula for Center of Mass by integration in Physics
Now, the rod is thin along the y and z directions. So, the color{Blue}y_{cm}=0 and color{Blue}z_{cm}=0. So, the position of center of mass of the rod is at (color{Blue}frac{2}{3}, 0, 0) m from one of the ends of the rod. In this way, one can find the center of mass of a continuous body by using the formula for center of mass by integration.
