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.)

Fg = (Gm1m2)/d^2
Fg = ((6.67x10^-11)*(71kg)*(48kg))/20^2
(solve)
Fg = 2.273136x10^-7/400
Fg = 5.68284x10^-10 N
(significant digits)
