Question

from the ground floor a man comes up to the fourth floor of a
building using a staircase another person comes up to the same
floor using the elevator neglect friction and compare work done in
the two cases

Rahul Jakhmola · Accepted Answer

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
