In a rotational experiment, a group takes a one-meter ruler with a uniformly distributed mass of 690 grams. A thread will be tied to the ruler 10 cm to the left of the center of mass. The group places a mass m1 = 400 g at the 15 cm position on the ruler. Then they place a mass m2 = 200 g at the 45 cm position. We are going to use a mass m3 = 75 g to balance the rule. Determine: a) The value of r1, r2 b) The value of r3 to be able to balance the rule c) Where on the ruler was the mass m3 placed?
