Answer:
Distance of the second child from the pivot point will be 2.66 m
Explanation:
We have given mass of the first child [tex]m_1=40kg[/tex]
Distance from the pivot point [tex]d_1=2m[/tex]
Mass of the second child [tex]m_2=30kg[/tex]
We have to find the distance of the second child from the pivot point
For this we have to balance the moment
So [tex]m_1d_1=m_2d_2[/tex]
[tex]40\times 2=30\times d_2[/tex]
[tex]d_2=2.66m[/tex]
So the distance of the second child from the pivot point point will be 2.66 m
