Question 40 NECO • 2020 • PHYSICS • objective

Two point charges are placed in the xy‑plane. Charge \(q_{1}=+2\,\mu\text{C}\) is at the origin \((0,0)\) and charge \(q_{2}=-3\,\mu\text{C}\) is at \((0,0.04\,\text{m})\). Determine the magnitude (in \(\text{N/C}\)) and direction (angle measured counter‑clockwise from the positive x‑axis) of the net electric field at point \(P\) located at \((0.06\,\text{m},0)\). Then calculate the work required to bring a test charge \(q_{t}=+1\,\mu\text{C}\) from infinity to point \(P\).

A. 2.96e6 N\/C, 90.0°, -0.074 J

Correct Answer B. 2.96e6 N/C, 76.7°, -0.074 J

C. 2.85e6 N\/C, 80.2°, -0.068 J

D. 3.10e6 N\/C, 70.0°, -0.080 J

Correct Answer

Correct Option:

2.96e6 N/C, 76.7°, -0.074 J
