Tom has a mass of 71.1 kg and Sally has a
mass of 59 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 · m2/kg2.
