Tom has a mass of 73. 9 kg and Sally has a mass of 59. 8 kg. Tom and Sally are standing 27. 9 m apart on a massless dance floor. Sally looks up and she sees Tom. She feels an attraction. If the attraction is gravitation, find its mag - nitude. Assume both can be replaced by spherical masses and that the gravitational constant is 6. 67259 * 10 ^ - 11 N · m^ 2 / kg^ 2. Answer in units of N.

Gravitational force (F) = Gxm1xm2 / r ^2. F = 6. 67259 * 10 ^ - 11 x 73.9 x 53.8 / (27.9) ^2 = 3.408x10^-10N which is negligible. Hope it is clear.
