Tom has a mass of 72.2 kg and Sally has a
mass of 49.4 kg. Tom and Sally are standing
17.4 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 magnitude. Assume both can be replaced by
spherical masses and that the gravitational
constant is 6.67259 × 10

Answer in units of N

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