Answer to Question #3017 in Mechanics | Relativity for KayLina

Question #3017
The gravitational force between two sumo wrestlers just before they collide (r=0.0250m) is 2.770*10^-3 N. <br>If one wrestler has a mass of 157.0 kg, what is his opponents mass?
Expert's answer
As F = (G m1 m2) / r2 ,
m2 = (r2 *F) / (G m1) = (0.0252*2.77*10-3)/(6.673&times;10-11 *157) = 165.2 kg.
