Homework Help: Potential energy problem pls help

  1. May 25, 2009 #1
    The potential energy in space is given as a function of polar coordinates by the following:

    U(r , therta) = Acos therta / r^2

    Given that A = 46 N∙m3, determine the x-component of the corresponding force at the location x = 1.7 m, y = 1.2 m.

    pls derive a formula to solve this equation
