Calculate the mechanical advantage of a lever where 5 N of input force is needed to move a 10 N box using that lever.?

The mechanical advantage of the lever is calculated by dividing the output force by the input force. In this case, the output force is 10 N and the input force is 5 N, so the mechanical advantage would be 10 N / 5 N = 2. This means that the lever provides a mechanical advantage of 2, making it easier to lift the box.
