You apply 100.0 n of force to a machine. the machine applies 20.0 n of force to the load. what is the mechanical advantage of the machine?
a) 200.0
b)80.0
c)5.00
d)0.200

The correct answer is option d.

Explanation:

Mechanical advantage of a machine is defined as ratio of force exerted by the machine to the force exerted on the machine.

Here we have applied  100.0 N of force on a machine and machine exerted the force 20.0 N in return.So, the mechanical advantage of the machine is ;

Force exerted by machine = 20.0 N

Force exerted on machine = 100.0 N

0.200 is the mechanical advantage of the machine.
