Electric Flux & Gauss's Law
Given below are two statements:
Statement I: An electric dipole is placed at the center of a hollow sphere. The flux of the electric field through the sphere is zero but the electric field is not zero anywhere in the sphere. Statement II: If R is the radius of a solid metallic sphere and Q be the total charge on it. The electric field at any point on the spherical surface of radius r (< R) is zero but the electric flux passing through this closed spherical surface of radius r is not zero.
In the light of the above statements, choose the correct answer from the options given below:
Show answer and solution
Answer: (c)
- Statement I: dipole has net charge zero, so flux is zero, but the dipole field is non-zero at points in the sphere. True.
- Statement II: inside a conductor for , so and flux is also zero. The claim that flux is not zero is false.
- So the answer is (c).
