A 100-meter long ruler has a fixed axis of rotation at 50 m (the center of the ruler) and from left to right it has markings for every 1 meter. A 4 kg mass is located at the 10 m marker, a 5 kg mass is located at the 75 m marker. Where would you place a 3 kg mass to force the system to be in equilibrium?
