Question

You lift a suitcase from the floor and keep it on a table. The work done by you on the suitcase does not depend on:

• A. The path taken by the suitcase
• B. The time taken by you in doing so
• C. The weight of the suitcase
• D. Your weight

Answer 1

Answer: (A), (B), (D)

Your weight
The time taken by you in doing so
The path taken by the suitcase

While lifting an object from ground work is done by us on the suitcase is given by
$W=mgh$
where variables have their usual meanings.
Since gravitational force is a conservative force. Hence, work done in lifting a suitcase from the floor and keeping it on a table depends on weight of suitcase and height of floor from top of the table but independent of the path taken by the suitcase or the time taken in doing the work or weight of person.
