Question

The work done by a charge of 10μC with a potential 4.386 is (in μJ)

(a) 32.86

(b) 43.86

(c) 54.68

(d) 65.68

I had been asked this question by my school principal while I was bunking the class.

This is a very interesting question from Gauss Law in portion Electrostatic Fields of Electromagnetic Theory

Answer 1

The correct answer is (b) 43.86

The explanation is: By Gauss law principles, W = Q X V = 10 X 10^-6 X 4.386 = 43.86 X 10^-6 joule.
