    Evaluate: ∇(∇r(hat)/r) where r is a position vector

    Homework Statement Not using any Cartesian or any other coordinates but rather the facts that (see equations, r^ is the position vector).. Evaluate: ∇( ∇ . (r^ / r)) Homework Equations ∇ . r^ = 3, ∇ x r^ = 0, ∇r = r^ / r The Attempt at a Solution From the 3rd...
