A region of space has a uniform electric field generated by two parallel plates that carry equal but opposite charges. A point charge of magnitude |q| is moved by a hand from position A to position B at a constant speed. In that move, the charge experiences a positive change in electric potential and the work done by the hand on the charge is negative. What is the sign of the point charge and which of the two plates is positive one
