A parallel plate capacitor of capacity `5 mu F` and plate separation `6 cm` is connected to a `1V` battery and is charged. A dielectric of dielectric constant `4` and thickness `4 cm` is introduced into the capacitor. The additional charge that flows into the capacitor from the battery is.

Options

A. `2 mu C`
B. `3 mu C`
C. `5 mu C`
D. `10 mu C`

Answer

C

Explanation

`q_(1)=cv,q_(2)=C^(/)V,(c)/(c^(/))=(d-t(t)/(K))/(d),Delta q=q_(2)-q_(1)`.
