You lift a suitcase from the floor and keep it on a table. The work done by you on the suitcase depends on

When lifting the suitcase, the force applied is equal to its weight (mg) and the displacement is the height (h) of the table from the floor. Since the force and displacement are in the same direction(θ =0⁰), we get: Work = mg × h
Thus, the work done depends on both the weight of the suitcase (a) and the height of the table (b), but not on the time taken (c). Correct answer: (d) Both (a) and (b).
