Answer the questions. "DO NOT SEND THE SIMILAR QUEIRIES"
Q.8. From the ground floor, a man comes up to the fourth floor of a building using a staircase. Another man comes up to the same floor using an elevator. Neglecting friction, compare the work done in the two cases.

Dear Student ,


The work done is equal to the change in potential energy.

The final potential energy is gravitational potential energy  (= mgh).
Now, as the height from ground is same, the difference in potential energy will come only due to the difference in mass of the persons. So, the potential energy will be the ratio of the masses of the two persons.
Regards
