Gravitational force between 2 people

    [SOLVED] Gravitational force between 2 people

    OK, this is my first time doing this so I'm completely lost.

    1. The problem statement, all variables and given/known data
    Find the force of attraction between a 60kg student and another student of mass 80kg, 1.4m away.

    2. Relevant equations
    G = 6.67 * 10[tex]^-11[/tex] Nm[tex]^2[/tex]/kg[tex]^2[/tex]

    Fg = [tex]\frac{Gm_1m_2}{r^2}[/tex]


    3. The attempt at a solution
    I tried [6.67 * 10^-11 (60kg)(80kg)] / 1.4m

    But I'm wrong.

    Your help is appreciated.

    r^2, mate; not r.
