A 65 g meter stick has two masses, each 250 g placed upon it. The first is located at 72 cm and the second located at 41 cm. Where should you place your finger if you wished to balance the meter stick? Give your answer in cm.
You must place your finger where the moments due to the masses on opposite sides are equal.
Write an equation that states that requirement, with the location of the finger as the unknown. Then solve it.
