Consider two celestial bodies that have equal masses and experience a gravitational force of 85.0 N towards one another. If their center are 36.0 mm apart, determine each of their masses.

F = G  m1 m2 / r2       and m1 = m2

 

F * r/G   =  m2               F = 85   N      r = .036 m      G = 6.67430 x 10-11   N m2 / kg2

 

85 * (.036)2  / (6.67430 x 10-11)    = m2     <====== NOTE:    m2    ,    Also 'm' will have  kg  units

  

 

You should be able to take it from here !
