Homework Help: Need help with assignment force question

  1. Jun 8, 2005 #1
    I am stumped on this question. Can anyone advise?

    The electric charge of an electron is -1.6 X 10 to the -19 power C.
    What is the force exerted between two electrons separated by one meter?

    The electrostatic force between two charged particles is
    [tex]F=\frac{q_1.q_2}{4\pi\epsilon_0.d^2}[/tex]
    where [tex]\epsilon_0[/tex] is the permitivity of free space and
    [tex]\kappa = \frac{1}{4\pi\epsilon_0} = 8.9876.10^9 N m^2 C^{-2}[/tex]
