Homework Help: Work and electric potential in a moving charge

  1. Jul 12, 2012 #1
    1. Explain briefly the relationship between electric potential and work in moving a positive charge q from point A to point B in an electric field

    Should I explain that work is potential energy plus kinetic energy? is it asking for that?
    and also, does the fact that it's a positive charge moving change anything? I'm confused
    help

    Did this come with a diagram? The direction of the E-field from point A to point B makes a big difference. Is the E field assumed to be uniform?

    Lots of info missing here unless you are supposed to go through all the general E-field orientations on your own.

    I just had this exact same question on a physics test today. Word for word, and I've been looking for the answer. Any luck?

    You need to know the definition of electric potential .
