    Answer:

     20N

    Explanation:

    Given parameters:

    Work done  = 200J

    Distance moved  = 10m

    Unknown:

    Amount of force applied  =?

    Solution:

    Work done is the force applied on a body to move it in the direction of the force.

          Work done  = force x distance

    The unit of work done is in joules

    Since the unknown is force, we make it the subject of the expression;

               Force  = \frac{Work done}{distance}

               Force  = \frac{200}{10}   =  20N
