Question

Ram goes from ground floor to his office building to fourth floor on foot Shyam uses lift for the same if the masses of Ram and Shyam are equal in which as more work has been done ​

Answer 1

Answer:

Ram and Shyam both will be do same work.

Explanation:

Given that

Mass of Ram and Shyam is same and lets take their mass is m kg.

Lets take the height of the forth floor of the building is at h m height from the ground floor.

Acceleration due to gravity = g m/s²

As we know that work done by a force given as

W = F.d

F=force

d=Displacement

Here F = m g ( downward)

d=  - h ( upward)

The force

F=  - m g h

Therefore Ram and Shyam both will be do same work.
