Answer:
L₁ = W×L / w
Explanation:
The scenario is shown in the image below.
<u>At the pivot point, the torque acting on this point must be zero so that there will be easy back and forth without the heavier child.</u>
<u>Torque created by lighter child + Torque created by the heavier child = 0</u>
Thus,
According to the axis system, the heavier child is left to the pivot (origin), so,
W×(- L ) + w× L₁ = 0
So,
<u>L₁ = W×L / w</u>
