Two forces F1 and F2 are applied to a plank that supports a body of mass m, as shown in the figure. The distances between these forces and the body of mass m are L1 and L2, respectively.
A. The values of F1 and F2 in static equilibrium depend on the choice of the axis of rotation.
B. In static equilibrium F1 = F2 for any values of L1 and L2.
C. The value of the sum (F1+ F2) that corresponds to static equilibrium is indepdendent of L1 and L2.
D. In static equilibrium, if L1 > L2, then F1 > F2.
