Question

Apollo and Artemis are playing on the teeter - totter in their schools playground. They both have approximately the same mass. They are sitting on either side of the teeter - totter at about the same distance from the teeter - totter pivot point. The teeter-totter is going up and down and they are having a great time! Mercury, the new kid in school, wanders by. Since they are very friendly kids, Apollo and Artemis ask Mercury to join them. Mercury joins Artemis on her side of the teeter-totter and sits next to her. What should Apollo do in order to keep the fun going?

a) move farther from the teeter-totters pivot point in order to balance out the new smaller torque provided by Mercury and Artemis.
b) move farther from the teeter-totters pivot point in order to balance out the new larger torque provided by Mercury and Artemis.
c) move closer to the teeter-totters pivot point in order to balance out the new smaller torque provided by Mercury and Artemis.
d) move closer to the teeter-totters pivot point in order to balance out the new larger torque provided by Mercury and Artemis.

T = Force * distance

Since on the other side two of his friends are sitting so he has to balance large torque

so in order to balance larger torque Arternis has to move farther from the teeter-totter's pivot point in order to balance out the new larger torque
