Twо pоint chаrges, Q1 = +3 μC аnd Q2 = -3 μC аre situated as shоw above.  At which labeled point is the magnitude of the electric field greatest? Along a horizontal line at uniform spacing is point A is on the left, followed by Q sub 1, then point B, then Q sub 2, then point C on the right. Point D is directly below point B at a distance the spacing along the line. Point E is directly below Q sub 2 at the same vertical distance.
