9. Two weights are placed on opposite sides of a seesaw which has a pivot in the middle (similar to figure 8-43 in the text). The heavy weight (21.0 kg) is placed 1.2m to the left of the pivot, and the lighter weight (15.0 kg) is placed 1.9 m to the right of the pivot. What is the net torque due to the weights at the moment they are placed on the seesaw? Remember, that torques which rotate an object counterclockwise are positive, and torques which rotate an object clockwise are negative.
