In a hydraulic press, the ratio of the cross-sectional area of the large piston to that of the small piston is 50. If a force of 100 N is exerted on the small piston, the maximum force exerted by the large piston is:

In a hydraulic press, if the radius of the large piston is 4 times that of the small piston, the mechanical advantage is:
