Question 28 GCE_MODEL_QUESTIONS_VOL1 • 2024 • PHYSICS • objective

Two point charges are fixed in air: a charge \(q_1 = +2\ \mu\text{C}\) at the origin and a charge \(q_2 = -3\ \mu\text{C}\) at the point \((0,\ 0.04\ \text{m})\). A test charge \(q = +1\ \text{nC}\) is placed at point \(P\) with coordinates \((0.03\ \text{m},\ 0)\).\n\n(a) Determine the magnitude and direction (angle measured north of east) of the net electric field at \(P\).\n(b) Find the force on the test charge at \(P\).\n(c) Calculate the work required to bring the test charge from infinity to \(P\).\nGive numerical answers to three significant figures and state units.

Answer Options

A. E = 1.45×10^7 N C⁻¹ at 28.5° north of east; F = 1.45×10⁻2 N at 28.5° north of east; W = 5.50×10⁻5 J
B. E = 1.80×10^7 N C⁻¹ at 35.0° north of east; F = 1.80×10⁻2 N at 35.0° north of east; W = 6.40×10⁻5 J
C. E = 1.60×10^7 N C⁻¹ at 40.2° north of east; F = 1.60×10⁻2 N at 40.2° north of east; W = 5.90×10⁻5 J
Correct Answer D. E = 1.60×10^7 N C⁻¹ at 32.7° north of east; F = 1.60×10⁻2 N at 32.7° north of east; W = 6.00×10⁻5 J
