Homework Help: What is the electric force between the balloon and the denim when the two are separat

  1. Mar 1, 2010 #1
    1. The problem statement, all variables and given/known data

    A balloon rubbed against denim gains a
    charge of −2.0 μC.
    The Coulomb constant is 8.98755 ×
    109 N · m2/C2.
    What is the electric force between the bal-
    loon and the denim when the two are sepa-
    rated by a distance of 6.0 cm? (Assume that
    the charges are located at a point.)
    Answer in units of N.

    2. Relevant equations

    q=n.e
    Fe=kq1q2/r^2
    e=Fe/q


    3. The attempt at a solution

    i tried plugging everything in but they were wrong when i checked them. please explain to me what i did wrong! thx .

    Show your calculations. With out that it is not possible to say what you did wrong.
