PhysicsElectrostatic Potential and CapacitanceMHT CET

Statement 1: A parallel plate capacitor is connected across battery through a key. A dielectric slab of constant is introduced between the plates. The energy which is stored becomes times Statement 2: The surface density of charge on the plate remains constant or unchanged

Answer: (C)

Solution

With the battery connected is constant and , so becomes times (Statement 1 true); the charge also becomes times,
