Two point charges are placed on the y‑axis: a charge \(+8\,\mu\text{C}\) at the origin O and a charge \(-2\,\mu\text{C}\) at point B (0, 0.12 m). (a) Find the point on the y‑axis between the charges where the net electric field is zero. (b) Calculate the electric potential at that point. (Take \(k = 9.0\times10^{9}\ \text{N m}^{2}\text{C}^{-2}\).)

A. y = 0.04 m; V = 2.8×10^5 V

B. y = 0.10 m; V = 5.0×10^5 V

Correct Answer C. y = 0.08 m; V = 4.5×10^5 V

D. y = 0.06 m; V = 3.6×10^5 V

Correct Answer

Correct Option:

y = 0.08 m; V = 4.5×10^5 V
