Question 19
Question MCQ▾
Figure given below shows two identical parallel plate capacitors connected to a battery with switch S closed. The switch is now opened and the free space between the plates of capacitors is filled with a dielectric of dielectric constant 3. What will be the ratio of total electrostatic energy stored in both capacitors before and after the introduction of the dielectric?

c. | 5: 3 | |
d. | 5: 1 |
Question 20
Question Assertion-Reason▾
Assertion(Ꭺ)
If the distance between parallel plates of a capacitor is halved and dielectric constant is made three times, then the capacitance becomes 6 times.
Reason(Ꭱ)
Capacity of the capacitor does not depend upon the nature of the material of plates.
