Answer:
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.
\(\phi =\frac{\text{Force exerted by machine}}{\text{Force exerted on machine}}\)
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
\(\phi =\frac{20.0 N}{100.0 N}=0.200\)
0.200 is the mechanical advantage of the machine.
