Homework Help: Potential Energy and the Electric Potential Difference

  1. Jul 13, 2008 #1
    I'm back again this week with a problem:

    A particle has a charge of +1.5 Micro Coulombs and moves from point A to point B, a distance of .20 m. The particle experiences a constant electric force, and its motion is along the line of action of the force. The difference between the particle's electric potential energy at A and B is EPEA - EPEB = +9.0x10-4 J. (a) Find the magnitude and direction of the electric force that acts on the particle. (b) Find the magnitude and direction of the electric field that the particle experiences.

    What have you done regarding this? How does the force exerted by the E-field relate to its electric potential energy?
