The larger ball in the picture has a mass m1 = 30 kg while the smaller ball has a mass m2 = 10 kg. (a) If the larger ball is placed 1 m away from the fulcrum, how far away from the fulcrum must the smaller ball be placed in order for the seesaw to be in equilibrium? Here the fulcrum is in the middle of the seesaw. (b) Now the fulcrum is located one fourth of the way from the left end of the plank and the balls are placed at either end. If the larger ball has the same mass as in part (a), what must the mass of the smaller ball be in order for the seesaw to be in equilibrium? Ignore the mass of the plank.
