A charge of 6.00 × 10–9 C and a charge of –3.00 × 10–9 C are separated by a distance of 60.0 cm. Find the position at which a third charge of 12.0 × 10–9 C can be placed so that the net electrostatic force on it is zero. ( x = 1.45 m beyond the –3.00 nC charge) Can you please explain step by step and add a drawing for this too? The answers are in the brackets. Thanks...
