The Potential of a point

    1. The problem statement, all variables and given/known data
    Point X is 0.25m away from a point charge of +4.7 X 10-8C, point Y is 0.65m away. What is the potential of point X with respect to point Y?


    2. Relevant equations
    V= kQ/d


    3. The attempt at a solution
    I was able to find the potential of X using V=kQ/d with respect to the point charge, which equals 1.7 X 103 V, but I'm not sure as to how to find it with respect to the Y point.

    Welcome to PF!

    Hi phm! Welcome to PF! :smile:
    The whole point of having potentials is that they don't depend on path (so they are only defined for conservative forces) …

    so the potentials just add and subtract as ordinary scalars (ordinary numbers) …

    just like gravitational potential energy! :wink:
