One can create an electric field that at a point $P$ in empty space points directly toward $P$ at all nearby points. $T$ or F? (Such a field would be very cool because we could use such a field to suspend a charged object in empty space so that it would float without touching anything!)

Question

Quizplus · Accepted Answer

An electric field originates from positive charges and terminates on negative charges, and its direction is defined as the direction a positive charge would move if placed in the field. Therefore, an electric field cannot point towards a single point in empty space from all directions, as this would imply a convergence of field lines without a source, contradicting Maxwell's equations.
