... Today’s PAL Draw below a point charge of +3q, and to the right, a point charge of –1q. Draw the electric field lines between them. Draw at least 10 lines evenly spread out. At a very large distance away, would a small positive test charge be attracted or repelled? If q is one electron’s worth of ...
