Problem 7PE

Two children of mass 20 kg and 30 kg sit balanced on a seesaw with the pivot point located at the center of the seesaw. If the children are separated by a distance of 3 m, at what distance from the pivot point is the small child sitting in order to maintain the balance?

Step-by-Step Solution:

Solution 7PE Step-by-step solution Step 1 of 2 The system is balanced, so net external torque acting on seesaw is zero. Or, Here, and is the torque acted on seesaw, and is the separation from pivoted point of children with mass and respectively.

Step 2 of 2
