An air capacitor C connected to a battery of e.m.f. V acquires a charge q and energy E. The capacitor is disconnected from the battery and a dielectric slab is placed between the plates. Which of the following statements is correct ?

While a capacitor remains connected to a battery and dielectric slab is applied between the plates, then

While a capacitor remains connected to a battery, a dielectric slab is slipped between the plates. Then

A parallel plate capacitor is charged by a battery after charging the capacitor, battery is disconnected and if a dielectric plate is inserted between the place of plates. Then which one of the following statements is not correct :

A parallel plate air capacitor is connected to a battery. If plates of the capacitor are pulled farther apart, then which of the following statements is/are correct ?

A parallel plate capacitor is charged by a battery after charging the capacitor, battery is disconnected and decrease the distance between the plates then which following statement is correct ?

A parallel plate capacitor is connected across a battery. Now, keeping the battery connected, a dielectric slab is inserted between the plates. In the process,

A parallel plate capacitor is connected across a battery. Now, keeping the battery connected, a dielectric slab is inserted between the plates. In the process,

A parallel plate capacitor having capacitance C farad is connected with a battery of emf V volts. Keeping the capacitor cannected with the battery, a dielectric slab of dielectric constant K is inserted between the plates. The dimensions of the slab are such that it fills the space between the capacitor plates. Then,

A parallel plate capacitor is connected across a 2V battery and charged. The battery is then disconnected and glass slab is introduced between the plates. Which of the following pairs of quantities decrease ?
