Two horizontal forces, and F₂, are acting on a box, but only is shown in the drawing. F₂ can point either to the right or to the left. The box moves only along the x axis. There is no friction between the box and the surface. Suppose that F₁ = +4.6 N and the mass of the box is 3.6 kg. Find the magnitude and direction of F₂ when the acceleration of the box is (a) +6.9 m/s², (b) -6.9 m/s², and (c) 0 m/s².
