Homework Help: Physics Question with Protons and Charge.

  1. Apr 11, 2012 #1
    Two negative electric charges, (Charge A on the left, and Charge B on the right) each with a charge of 7.4 x 10-5 Coulombs are fixed at a distance of 2.7 meters from each other. Find the electric force of charge A on charge B. (Don't forget, if the force points to the left, then the force is negative).

    Find the electric force of Charge B on Charge A.

    Suppose Charge B has a mass of 0.05 kilograms, and is now allowed to move freely. Find the acceleration of Charge B.

    I am so lost. If someone can point me in the right direction it will be much appreciated. Thank you very much.
