JEE PYQ: Electrostatics Question 15
Question 15 - 2021 (26 Feb Shift 2)
Given below are two statements:
Statement - I: An electric dipole is placed at the centre of a hollow sphere. The flux of 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.
(1) Statement I is true but Statement II is false
(2) Statement I is false but Statement II is true
(3) Both Statement I and Statement II are true
(4) Both Statement I and Statement II are false
Show Answer
Answer: (1)
Solution
Statement I is correct: dipole has zero net charge so flux = 0, but field is non-zero inside. Statement II is incorrect: inside a conductor $E = 0$ and flux $= 0$ (no enclosed charge inside $r < R$).
