What is the resultant force on system of force 2N and 8N?

The resultant force on the system of forces 2N and 8N acting in the same direction is 10N (2N + 8N).


If the input force on a simple machine is 2n and the output force is 4n what is its mechanical advantage?

The mechanical advantage of the simple machine is 2, which is calculated as the output force divided by the input force (4n/2n = 2).


What work is done when we apply a force of 5n and move in the direction of the force 2n?

The work done is calculated by multiplying the force applied in the direction of motion by the distance moved. In this case, the work done would be 10 Joules (5 N * 2 m), as the force and displacement are in the same direction.


Compare the amount of work done when a force of 2n moves an object 3 meters with the work done when a force of 3n moves an object 2 meters?

When a force of 2N moves an object 3 meters, the work done is 6 Joules (2N * 3m). When a force of 3N moves an object 2 meters, the work done is 6 Joules as well (3N * 2m). Consequently, the same amount of work (6 Joules) is done in both scenarios.


Place 4n worth of force 0.2m from the fulcrum where would you have to place 2n in order for the lever to balance?

The force is equal to the mass times your lever arm. If 4n is placed 0.2m from the fulcrum, you have 0.8 force units on you lever arm. This would imply that a mass of 2n should be placed 0.4m from the fulcrum in the opposite direction. This would give you 0.8 force units on both sides, thereby balancing the lever.
