    Explanation:

    Definition of work done states that,

    Work done on an object is the force applied on that object in the direction of Displacement of the object.

    means that,

    W = F. dS (Dot product of Force and displacement)

    When the wall is acted upon by the force of 20 N, Wall does not move,

    Thus, displacement of the wall is zero.

    So, W = 20*0 = 0.

    Thus, Work done on the wall is zero.
