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
A
Charge and potential difference
B
Potential difference and energy stored
C
Energy stored and capacitance
D
Capacitance and charge
Answer
Potential difference and energy stored
Explanation
Solution
The introduction of a dielectric slab increases the capacitance. The charge remains unchanged. Potential difference and energy stored decreases
