A sled of mass \(m\) rests on a flat horizontal surface where the coefficient of static friction is \(\mu_s\). In Scenario 1, a force of magnitude \(F\) is applied to the sled at an angle \(\theta\) above the horizontal, where \(0 < \theta < 90^\circ\) and \(F\sin\theta < mg\). In Scenario 2, a force of the same magnitude \(F\) is applied to the sled at the same angle \(\theta\) below the horizontal. Which of the following correctly pairs the difference in the normal force exerted on the sled, \(F_{N,\text{below}} - F_{N,\text{above}}\), with the scenario and condition under which the sled cannot be made to slide from rest regardless of the magnitude of \(F\)?
