Homework Help: Help on electric problems

  1. Oct 14, 2004 #1
    I missed the material for these couple of problems. If someone could help explain how to solve them I would much appreciate it. :cool:

    1.) A charge of +2 x 10^-6 C is 20cm from a charge of -3 x 10^-6 C. Find the magnitude and direction of the force on each charge.

    2.) A 120-V electric coffeepot draws a current of 0.6 A. What is the resistance of its heating element?

    Look up Coulomb's law.
    Look up Ohm's law.

    [tex]F_E = \frac{Q_1Q_2}{4\pi\epsilon_0r^2}[/tex]

    [tex]V = IR[/tex]

    Also Newtons Third Law should help you determine the force on EACH charge to your first question.
