The weight of Mia on the balanced seesaw is 600 N.
Principle of moment
The principle of moment states that the sum of clockwise moment is equal to sum of anticlockwise moment.
Position of mia = 1 m
Position of Blessy = 1.5 m
The weight of Mia is calculated as follows;
W₁r₁ = W₂r₂
[tex]W_1 = \frac{W_2 r_2}{r_1} \\\\W_1 = \frac{400 \times 1.5}{1} \\\\W_1 = 600 \ N[/tex]
Thus, the weight of Mia on the balanced seesaw is 600 N.
