Homework Help: Gravitational attraction

  1. Feb 1, 2010 #1
    1. The problem statement, all variables and given/known data
    what is the gravitational attraction between two students with masses of 70 kg and 50 kg, if they are 1.5 m apart?

    2. Relevant equations
    Fg=Gm1m2/r^2


    3. The attempt at a solution
    so my Fg is 6.67 x 10^-11, m1 is 70 kg and m2 is 50 kg. for my radius, do i just use the 1.5 m and plug it into the formula? or no i need to do something else?
