Question 23 NECO_MODEL_QUESTIONS_VOL1 • 2020 • PHYSICS • objective

Three point charges are placed at the vertices of a right‑angled triangle. Vertex A is at the origin, vertex B lies 0.20 m along the positive x‑axis, and vertex C lies 0.30 m along the positive y‑axis. The charges are: \(q_{A}=+2\ \mu\text{C}\) at A, \(q_{B}=-3\ \mu\text{C}\) at B, and \(q_{C}=+4\ \mu\text{C}\) at C. Determine the magnitude and direction of the net electric field at point A due to the charges at B and C.

Answer Options

A. 8.2×10^5 N/C, 31° above the +x axis
B. 7.9×10^5 N/C, 45° below the +x axis
Correct Answer C. 7.9×10^5 N/C, 31° below the +x axis
D. 6.5×10^5 N/C, 31° below the +x axis
Correct Answer
C
Correct Option:
7.9×10^5 N/C, 31° below the +x axis
