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