A sign of weight 200N hangs at rest from two identical cables that are attached to the ceiling and make equal 30∘ angles with the horizontal. Which of the following relationships among the forces must be true for the sign to remain in equilibrium?
(a) Each cable must exert a tension of 115N (approximately).
(b) Each cable must exert a tension of 200N.
(c) Each cable must exert a tension of 100N.
(d) Each cable must exert a tension of 400N.
