Torque The objective is to balance a ruler with a pivot point located at the center.
1) If a 200 g mass is located at 32 cm mark and a 100 g mass is located at the 48 cm mark of a ruler, where do you place the 150 g mass so that the ruler is balanced?
2) If a 100 g mass is located at 32 cm mark and a 200 g mass is located at the 48 cm mark of a ruler, where do you place the 150 g mass so that the ruler is balanced?
