5. Three forces act on the sphere: the tension force GTof the rope (acting along the rope), the force of the wall NFG(acting horizontally away from the wall), and the force of gravity mgG(acting downward). Since the sphere is in equilibrium they sum to zero. Let θbe the angle between the rope and the vertical. Then Newton’s second law givesvertical component :Tcos – mg= 0horizontal component: FN– Tsin = 0.(a) We solve the first equation for the tension:
