AIIMS 2011 Physics Gauss's Law Assertion Reason Question
Assertion : Gauss’s law can’t be used to calculate electric field near an electric dipole. Reason : Electric dipole don’t have symmetrical charge distribution.
Both assertion and reason are true and reason is the correct explanation of assertion
Both assertion and reason are true but reason is not the correct explanation of assertion
Assertion is true but reason is false
Both assertion and reason are false
Correct Answer
Detailed Explanation
Gauss's law is applicable for any closed surface. Gauss's law is most useful in situation where the charge distribution has spherical or cylindrical symmetry or is distributed uniformly over the plane. Whereas electric dipole is a system of two equal and opposite point charges separated by a very small and finite distance.
