Question 42 NECO_MODEL_QUESTIONS_VOL1 • 2017 • PHYSICS • objective

Two point charges are placed on the \(x\)-axis. A charge \(+8\;\mu\text{C}\) is at the origin and a charge \(-12\;\mu\text{C}\) is at \(x = 0.20\;\text{m}\).\n(i) Find the position on the axis where the net electric field is zero.\n(ii) Calculate the electric potential at that point relative to infinity.

Answer Options

Correct Answer A. x = 0.090 m (between the charges); V ≈ -1.8×10⁵ V
B. x = 0.050 m (between the charges); V ≈ -1.2×10⁵ V
C. x = 0.130 m (between the charges); V ≈ -2.4×10⁵ V
D. x = 0.070 m (between the charges); V ≈ -1.5×10⁵ V
Correct Answer
A
Correct Option:
x = 0.090 m (between the charges); V ≈ -1.8×10⁵ V
