i) Assume that a ruler(100cm) is asymmetrical, and it is balanced at the 45 cm mark (at the center of mass). Now, mass M is hung on the ruler at 100 cm mark. Where should you hang mass 1.82M so the system remains in the equilibrium?
ii) Assume that the ruler is asymmetrical, balancing at the 63.5 cm mark. The ruler is now supported at the 45.9 cm mark, and a mass of 404 g is located at the 27.2 cm mark. Determine the mass of the ruler.
