Answer 1

Correct Question:

A man standing still at a bus stop with heavy suitcase in his hands make him tiresome but he does no work. Explain why.

Solution:

The man got tired only by holding the heavy suitcase even though he was just standing still at bus stop.

This happened so, because we know that Work done = force × displacement.

He was standing still at the bus stop and wasn't moving so there was no displacement and he as he was standing still the force was acting perpendicular. So, that's the reason why he got tired even though no work was done by him.
