Question 27 NECO_MODEL_QUESTIONS_VOL1 • 2021 • PHYSICS • objective

Two point charges, \(q_{1}=+8\;\mu\text{C}\) placed at the origin and \(q_{2}=-2\;\mu\text{C}\) placed on the x‑axis at \(x=0.30\;\text{m}\), are fixed in vacuum. (a) Find all points on the x‑axis where the net electric field is zero. (b) At the point that lies between the two charges, calculate the electric potential relative to infinity.

Answer Options

A. x = 0.10 m and 0.80 m; V = 2.2×10^5 V
B. x = 0.25 m and 0.55 m; V = 1.6×10^5 V
C. x = 0.15 m and 0.75 m; V = 2.0×10^5 V
Correct Answer D. x = 0.20 m and 0.60 m; V = 1.8×10^5 V
Correct Answer
D
Correct Option:
x = 0.20 m and 0.60 m; V = 1.8×10^5 V
