When the mother finds the distance l from the previous part it turns out to be greater than lend, the distance from the pivot to the end of the seesaw. hence, even with the child of weight w at the very end of the seesaw the twins exert more torque than the heavier child does. the mother now elects to balance the seesaw by pushing sideways on an ornament (the circle above the center) that is a height h above the pivot. with what force in the rightwards direction, fx, should the mother push? note that if you think the force exerted by the mother should be toward the left, your final answer fx should be negative.
