A heavy ball suspended by a cable is pulled to the side by a horizontal force F as shown in Fig. 9-43. If angle 0 is small, the magnitude of the force F can be less than the weight of the ball because: (a) the force holds up only part of the ball's weight. (b) even though the ball is stationary, it is not really in equilibrium. (c) F is equal to only the x component of the tension in the cable. (d) the original statement is not true. To move the ball, F must be at least equal to the ball's weight. FIGURE 9–43 MisConceptual Question 4.
