A traffic light of mass 12kg hangs motionless from the ceiling, suspended by two identical cables that make equal angles with the horizontal. Which set of forces acts on the traffic light?
(a) The weight acts downward, and a single tension force acts upward along the vertical.
(b) The weight acts downward, and two tension forces act upward along the cables toward the ceiling.
(c) The weight acts downward, and two tension forces act along the cables but pull toward the traffic light.
(d) The weight acts downward, and two vertical tension forces act upward, one from each cable.
