Question: In the electrostatic case, the expressions F = del(p.E) and F = (p.del)E are equivalent:
I am having trouble with how to show they are equivalent
In the second equation, I expanded it out to give F= px (dE/dx) + py (dE/dy) + pz(dE/dz)
Any help as to how to do this would be much appreciated
thanks
