Question 22 IGCSE_MODEL_QUESTIONS_VOL1 • 2025 • PHYSICS • objective

Two point charges are placed on the x‑axis. A charge \(q_{1}=+8.0\ \text{nC}\) is at the origin, and a charge \(q_{2}=-2.0\ \text{nC}\) is at \(x=0.20\ \text{m}\). Find the position on the x‑axis where the net electric field has magnitude \(5.0\times10^{4}\ \text{N C}^{-1}\) and is directed to the right. Then calculate the electric potential at that point due to both charges (give the potential in volts, to three significant figures).

Answer Options

A. x = 0.0450 m, V = 2.10×10³ V
B. x = 0.0250 m, V = 1.20×10³ V
Correct Answer C. x = 0.0382 m, V = 1.77×10³ V
D. x = 0.0382 m, V = 2.00×10³ V
Correct Answer
C
Correct Option:
x = 0.0382 m, V = 1.77×10³ V
