Work is defined as the force applied to an object times the distance over which that force is applied, and it can be calculated using the formula:
\[ \text{Work} = \text{Force} \times \text{Distance} \times \cos(\theta) \]
where \( \theta \) is the angle between the force and the direction of movement. In this case, the wall does not move, which means the distance is 0 meters.
Since work is done only when there is displacement in the direction of the applied force, and in this scenario, the wall does not move despite the force being applied:
\[ \text{Work} = 500 , \text{N} \times 0 , \text{m} = 0 , \text{joules} \]
Therefore, the answer is 0 joules.
