Aheavy ball suspended by a cable is pulled to the side by a horizontal force f. if angle θ is small, the magnitude of the force f can be less than the weight of the ball because:
a. even though the ball is stationary, it is not really in equilibrium.
b. f is equal to only the x component of the tension in the cable.
c. the force holds up only part of the ball's weight.
d. the original statement is not true. to move the ball, f must be at least equal to the ball's weight.
