Identify the correct statements among the following:
(A) Gauss's law is valid for the closed surface only.
(B) It is not possible to derive Gauss's law from Coulomb's law
(C) The electric field inside a uniformly charged thin spherical shell is zero
(D) The flux is contributed by the electric charges outside the closed surface
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (A) and (C) only
(A) Correct — Gauss's law relates the net flux through a closed surface to the charge enclosed by it.
(B) Incorrect — Gauss's law can be derived from Coulomb's law (assuming the inverse-square law and superposition).
(C) Correct — Inside a uniformly charged thin spherical shell the electric field is zero.
(D) Incorrect — Charges outside a closed surface give zero net flux through that surface; only enclosed charges contribute.
∴ Correct statements: (A) and (C)
