FIGURE 7-2 Three Applied Forces, F₁ = 20

Multiple Choice

FIGURE 7-2 Three applied forces, F₁ = 20.0 N, F₂ = 40.0 N, and F₃ = 10.0 N act on an object with a mass of 2.00 kg which can move along an inclined plane as shown in the figure. The questions refer to the instant when the object has moved 0.600 m along the surface of the inclined plane in the upward direction. Neglect friction and use g = 10.0 m/s².
-Refer to Fig. 7-2. What is the amount of work done by the force F₃ as the object moves up the inclined plane?

A) 12.0 J
B) 16.0 J
C) 20.8 J
D) 0 J
E) 24.0 J
