Two charges are set on the x-axis 18.1 cm away from each other. The charges are 23.2 nC and -10.0 nC. Calculate the electric field at the point on the x-axis between the charges where the electric potential due to these two charges is zero. A) 7.83×10³ N/C B) 4.33×10⁴ N/C C) -6.46×10⁴ N/C D) 951 N/C
