Question

Which of the following statements is not true about Gauss’s law?

• A. Gauss’s law is true for any closed surface
• B. The term $q$ on the right side of Gauss’s law includes the sum of all charges enclosed by the surface
• C. Gauss’s law is not much useful in calculating electrostatic field when the system has some symmetry
• D. Gauss’s law is based on the inverse square dependence on distance contained in the coulomb’s law

Answer 1

Answer: (C)

Gauss’s law is often useful towards a much easier calculation of electrostatic field when the system has some symmetry. This is facilitated by the choice of a suitable Gaussian surface.
