Question

Coommmm it's a challenge for everyone for all students and moderator and all the experts give the answer of my 25th question .... Don't copy from Google

Answer 1

We know that work done against gravity = change in potential energy

Change in potential energy = m g h

h = change in height

As the change in height is the same for both men, both the men have done equal work against gravity.

Answer 2

The answer is here

=> There is written that against gravity means the potential energy. The formula of potential energy = m×g×h. If both of them have same mass. Means both of them have done same work against gravity.
