5. Three forces act on the sphere: the tension force G T of the rope (acting along the rope), the force of the wall N F G (acting horizontally away from the wall), and the force of gravity mg G (acting downward). Since the sphere is in equilibrium they sum to zero. Let θ be the angle between the rope and the vertical. Then Newton’s second law gives vertical component : T cos mg = 0 horizontal component: F N T sin = 0. (a) We solve the first equation for the tension:
