Lever shoulders are in equilibrium equal to 10 centimeters and 60 centimeters, more force 12n. Find less force.

According to the balance rule of the lever:
F1 / F2 = l2 / l1, where F1 is the force acting on the shoulder l1 (F1 = 12 N); F2 is the force acting on the arm l2 (N), l1 is the smaller arm of the lever (l1 = 10 cm), l1 is the larger arm of the lever (l2 = 60 cm).
Let us express and calculate the force acting on the lever arm l2:
F2 = F1 * l1 / l2 = 12 * 10/60 = 2 N.
Answer: The lesser force is 2 N.
