Two point charges are placed on the x‑axis: a charge \(+8\,\mu\text{C}\) at the origin and a charge \(-2\,\mu\text{C}\) at \(x = 0.12\,\text{m}\). (i) Find the position on the x‑axis where the net electric field is zero. (ii) At that point, calculate the electric potential (taking the potential at infinity as zero). (Use \(k = 9.0\times10^{9}\,\text{N m}^{2}\text{C}^{-2}\)).

Answer Options

A. x = 0.08 m; V = 2.0×10^5 V
B. x = 0.24 m; V = 2.5×10^5 V
C. x = 0.36 m; V = 1.0×10^5 V
Correct Answer D. x = 0.24 m; V = 1.5×10^5 V
Correct Answer
D
Correct Option:
x = 0.24 m; V = 1.5×10^5 V
