Question

raghav is trying to push the wall with all his strength. do you think work is done in the above situation. why?​

Answer 1

Answer:

Yes work is done if Raghav is trying to push with all his strength.

Answer 2

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.
