1. The problem statement, all variables and given/known data Suppose that F is the inverse square force field below, where c is a constant. F(r) = c*r/(|r|)^3 r = x i + y j + z k (a) Find the work done by F in moving an object from a point P1 along a path to a point P2 in terms of the distances d1 and d2 from these points to the origin. 2. Relevant equations 3. The attempt at a solution Well this is a conservative force because it is dealing with gravity. So i know that the solution is going to be something like F(d2-d1). But how do i write that out? I think that |r| just equals d1 or d2 depending on which one is selected. But how do i get r?
