Kenna Foster · Answer 1

The force that the elevator floor exerts on the man's feet

The force of gravity on the man

Explanation:

Only two force have to consider

1. Force of gravity on the man

2. Force that the elevator floor exerts on the man's feet

When a man stands on the elevator floor then it apply a normal force on the floor of elevator. We know that from Newtons third law, it states that every action have it same magnitude but opposite in direction reaction.
