Gravitational Potential Problem ( one simple yes/no question)

  1. Oct 20, 2009 #1
    1. The problem statement, all variables and given/known data

    When finding the gravitational potential of a thick walled hollow cylinder from the

    point P, located along the X-axis,

    can I find the Gravitational potential of a solid cylinder and then subtract the
    gravitational potential of a smaller (inner empty) cylinder?



    2. Relevant equations

    3. The attempt at a solution

    This is my attempt to answer a much complicated problem.
    I just need to make sure that I can subtract the two gravitational potential
    to find the gp of hollow thick cylinder.

    Any hint or help would be really appreciated thanks!

    Hi rockstar101! Welcome to PF! :wink:
    Yes … that's exactly the way to do it. :smile:

    is the gravitational potential measuring from a point on Z axis same as the gp measured on a point on X axis?

    (what happened to "one simple yes/no question"? :biggrin: :wink:)

    If the Y-axis is the axis of the cylinder, yes. :smile:
