Tom has a mass of 69.0 kg and Sally has a mass of 54.0 kg. Tom and Sally are standing 20.0 m apart on the dance floor. Sally looks up and sees Tom. She feels an attraction. If the attraction is gravitational, find its size. Assume that both Tom and Sally can be replaced by spherical masses. (Use G = 6.67 10-11 N · m2/kg2.)

F =G•m1•m2/R²
the gravitational constant G =6.67•10⁻¹¹ N•m²/kg²,
