[0/2 Points] Calculus 3 The force exerted by an electric charge at the origin on a charged particle at a point (
x,y,z
with position vector
r=(:x,y,z:)
is
F(r)=K(r)/(|)r|^(3)
where
K
is a constant. (See this example.) Find the work done as the particle moves along a straight line from
(4,0,0)
to
(4,4,5)
.
