Explanation Consider the figure given below. Write the expression for the total force in y direction. ∑ F y = F g 1 + F g 2 − F g (I) Here, F g 1 is the force acting at scale 1, F g 2 is the force acting at scale 2, F g is the force acting at the center of mass. Since the net torque is zero, the force y direction is zero. ∑ F y = F g 1 + F g 2 − F g = 0 (II) Write the expression for the net torque. ∑ τ = − F g 1 l + F g x + F g 2 x ′ = 0 (III) Here, l is the distance between the scales, x is the distance from foot to the center of mass, x ′ is the distance from foot to second scale. Conclusion: Substitute, 380 N for F g 1 , 320 N for F g 2 in equation (II) to find the value of F g
