Consider a person standing in an elevator that is moving upward at constant velocity \( \mathbf{v} \). The person of mass \( m \) has two forces acting upon him: the downward force \( m \mathrm{~g} \) due to gravity and the upward supporting force \( \mathbf{n} \) exerted by the floor of the elevator. Which force has the largest magnitude? Select all that apply 1. \( n \). 2. If \( \mathbf{v} \) is upward, \( m \mathbf{g}=0 \) 3. \( m \mathbf{g} \) 4. None these 5. They have the same magnitude. 6. If \( \mathbf{v} \) is upward, \( \mathbf{n}=0 \).
