Problem
A charge of +6 µC is fixed at x = 0 m and a charge of –3 µC is fixed at x = 0.30 m on a straight line in vacuum. At what distance from the +6 µC charge, measured along the line and on the side of the –3 µC charge, will a small positive test charge experience zero net electrostatic force?
(a) 0.60 m
(b) 0.72 m
(c) 1.02 m
(d) 0.30 m
