I'm very happy to read your post, because that's actually how i ended up doing it, though I certainly wasn't sure if it was right. Thanks very much, I really appreciate all your help!

Homework Statement The force exerted by an electric charge at the origin on a charged particle at point (x,y,z) with position vector r = <x,y,z> is F(r) = Kr / |r|^3 where K is a constant. Find the work done as the particle moves along a straight line from (2,0,0) to (2,1,5). Homework...

anyone?

Homework Statement This isn't really even a homework question..i've just been reviewing some general math concepts and this one has been driving me nuts..i haven't done math in a while. At time t = 1, a particle is located at position (1,3). If it moves in a velocity field F(x,y) =...
