COMEDK 2023 Evening Shift | Capacitor Question 9 | Physics

In the figure, first the capacitors are fully charged by closing the key $$\mathrm{K}$$. Then after opening the Key a dielectric material with dielectric constant 2 is filled in the space between the plates of both the capacitor. At this state the ratio of the Charge on the capacitor $$C_1$$ to that of $$C_2$$ is:

1 : 1

3 : 2

2 : 1

1 : 2

Two capacitors $$C_1$$ and $$C_2$$ are charged to 120 V and 200 V, respectively. When they are connected in parallel, it is found that potential on each one of them is zero. Therefore,

$$5C_1=3C_2$$

$$3C_1=5C_2$$

$$3C_1+5C_2=0$$

$$9C_1=4C_2$$
