A crate of mass \(m\) is placed on a horizontal scale that is fixed to the floor of an elevator. The elevator is moving upward, and its speed is decreasing. Let \(F_n\) be the magnitude of the normal force exerted by the scale on the crate and \(F_g\) be the magnitude of the gravitational force on the crate. Which of the following correctly describes the relationship between \(F_n\) and \(F_g\) and provides a valid justification?
