Answer : Mechanical advantage of the machine is 0.1
Explanation :
The force applied on to a machine is 250 N. This is the input force that is applied to the machine.
The machine applies a force of 25 N to an object. This shows the output force that is applied by the machine.
Mechanical advantage of the machine is defined as the ratio of the output force and the input force.



The correct option is (A) " 0.1 "
Hence, this is the required solution.
