Question

Which of the Pythagorean Theorem is valid in Electromagnetics? (a) |dot product| + |dot product| = 1 (b) |cross product| – |cross product| = 1 (c) |dot product|^2 + |cross product|^2 = 1 (d) |dot product| + |cross product| = 0 I had been asked this question during an interview for a job. The question is from Dot and Cross Product in chapter Vector Analysis and Applications 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 (c) |dot product|^2 + |cross product|^2 = 1 To explain I would say: Option |dot product|^2 + |cross product|^2 = 1 gives |cos|^2 + |sin|^2 = 1, which is the right answer.
