Question

Two friends of different masses are on the playground. They are playing on the seesaw and are able to balance it even though their masses are different. show answer No Attempt How are they able to balance on the seesaw? They are able to balance their individual energies. All of these. Their densities are the same. They are able to balance forces due to gravity. They are able to balance their individual momenta. They are able to balance torques due to gravity.

Answer 1

They are able to balance torques due to gravity.

`F_1 L_1 = F_2L_2`

Step-by-step explanation:

When two friends of different masses will balance themselves on see saw then at equilibrium position the see saw will remain horizontal

This condition will be torque equilibrium position where the see saw will not rotate

Here we can say

`F_1 L_1 = F_2L_2`

here we know that force is due to weight of two friends

and their positions are different with respect to the lever about which see saw is rotating

since both friends are of different weight so they will balance themselves are different positions as per above equation
