Two point charges are placed in the xy‑plane. Charge \(Q_{1}=+4\ \mu\text{C}\) is at the origin \((0,0)\) and charge \(Q_{2}=-6\ \mu\text{C}\) is at \((0,0.04\ \text{m})\). Determine the magnitude (in \(\text{N·C}^{-1}\)) and direction (angle measured counter‑clockwise from the positive x‑axis) of the net electric field at point \(P\) located at \((0.03\ \text{m},0)\).

Answer Options

A. Magnitude \(\approx 2.5\times10^{7}\ \text{N·C}^{-1}\); direction \(\approx 45^{\circ}\) above the positive x‑axis.
B. Magnitude \(\approx 3.2\times10^{7}\ \text{N·C}^{-1}\); direction \(\approx 20^{\circ}\) above the positive x‑axis.
C. Magnitude \(\approx 4.0\times10^{7}\ \text{N·C}^{-1}\); direction \(\approx 33^{\circ}\) below the positive x‑axis.
Correct Answer D. Magnitude \(\approx 3.2\times10^{7}\ \text{N·C}^{-1}\); direction \(\approx 33^{\circ}\) above the positive x‑axis.
Correct Answer
D
Correct Option:
Magnitude \(\approx 3.2\times10^{7}\ \text{N·C}^{-1}\); direction \(\approx 33^{\circ}\) above the positive x‑axis.
