A charge of +1.62 × 10-9 C is placed at the origin, and another charge of +6.27 × 10-9 C is placed at x = 2.4 m.
The value of the Coulomb constant is 8.98755 × 109 N · m2/C2.
Find the point (coordinate) between these two charges where a charge of +3.10 × 10-9 C should be placed so that the net electric force on it is zero. Answer in units of m.
