Column I gives certain situations in which capacitance of a capacitor is changed by different means. Column Il gives resulting effect under different conditions. Match the statements in column I with the corresponding statements in column II.
Column I
(A) The plates of a plane parallel capacitor are slowly pulled apart. The magnitude of electric field intensity inside the capacitor.
(B) The plates of a plane parallel plate capacitor are slowly pulled apart. The potential energy stored in the capacitor.
(C) The capacitance of an air filled plane parallel plate capacitor on insertion of dielectric
(D) A dielectric slab is inserted inside an air filled plane parallel plate capacitor. The potential energy stored in the capacitor.
Column II
(p) Increases if the capacitor is maintained at constant charge.
(q) Decreases if the capacitor is maintained at constant charge
(r) Increases if the capacitor is maintained at constant potential difference.
(s) Decreases if the capacitor is maintair at constant potential difference.
