Assertion: A parallel plate capacitor is connected across battery through a key. A dielectric slab of
\( \mathrm{P} \)
dielectric constant \( \mathrm{K} \) is introduced between the plates. The energy which is stored becomes \( \mathrm{K} \) times.
Reason: The surface density of charge on the plate remains constant or unchanged.
(1) If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
(2) If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
(3) If the Assertion is correct but Reason is incorrect.
(4) If both the Assertion and Reason are incorrect.
