Question

Find the electric field applied on a system with electrons having a velocity 5m/s subjected to a magnetic flux of 3.6 units. (a) 15 (b) 18 (c) 1.38 (d) 0.72 I had been asked this question in an online interview. I'm obligated to ask this question of Maxwell Law 1 topic in section Maxwell Equations of Electromagnetic Theory Select the correct answer from above options Electromagnetic Theory questions and answers, Electromagnetic Theory questions pdf, Electromagnetic Theory question bank, Electromagnetic Theory questions and answers pdf, mcq on Electromagnetic Theory pdf,electromagnetic theory book pdf,electromagnetic theory pdf notes,electromagnetic theory lecture notes,electromagnetic theory of light,maxwell electromagnetic theory,electromagnetic theory proposed by,electromagnetic theory engineering physics,electromagnetic theory nptel

Answer 1

Correct choice is (b) 18 Easiest explanation: The electric field intensity is the product of the velocity and the magnetic flux density. Thus E = v x B, on substituting v = 5 and B = 3.6, we get E = 5 x 3.6 = 18 units.
