Question

ram is trying to push the wall with all his strength. do you think force is applied inthe above case​

Answer 1

Answer:

Work done (W) = force ∗ displacement.

Hence, work is said to be done when there is displacement. In this case the wall does not displace from its position even though the force is applied and since displacement is zero work done is said to be zero.
