Homework Help: Work done moving an object in a field.

  1. May 7, 2010 #1
    1. The problem statement, all variables and given/known data
    Find the work done in moving an object in the field
    F = (2xy+z^3)i + x^2j + 3xz^2k
    from (1,-2,1) to (3,1,4)

    2. Relevant equations

    I have found p, the scalar potential to be x^2y+xz^3 , but don't know how to proceed from here. Do I just plug in the values so that I get ((9)(1)+(3)(64)) - ((1)(-2)+(1)(1)) = 202?

    3. The attempt at a solution

    Method looks fine although I would write some equations when writing it up.
