Question 32 IGCSE_MODEL_QUESTIONS_VOL1 • 2022 • PHYSICS • objective

A point charge \(q = 3\,\mu\text{C}\) is held \(0.05\,\text{m}\) above a large grounded conducting plate. Using the method of images, (a) find the magnitude of the electrostatic force on the charge due to the induced charges on the plate. (b) Calculate the work required to move the charge slowly from its initial position to a height of \(0.20\,\text{m}\) above the plate.

Answer Options

A. Force ≈ 10.2 N upward; work required ≈ 0.45 J
B. Force ≈ 8.09 N downward; work required ≈ 0.30 J
C. Force ≈ 5.00 N upward; work required ≈ 0.15 J
Correct Answer D. Force ≈ 8.09 N upward; work required ≈ 0.30 J
Correct Answer
D
Correct Option:
Force ≈ 8.09 N upward; work required ≈ 0.30 J
