In the beginning the space between the plates of a parallel plate capacitor contains air and thereafter it is filled up with a medium of dielectric constant K. Then ......

Options

A. The electric field and the capacitance become K times.
B. The electric field becomes `(1)/(K)` times and the capacitance becomes K times.
C. The electric field becomes K times and the capacitance becomes `(1)/(K)` times.
D. The electric field and the capacitance become `(1)/(K)` times

Answer

A, B, C, D

Explanation

`E = (E_(0))/(K)` and `C = KC_(0)`
Where `E_(0)` = Electric field for air medium.
`C_(0)` = Capacitance of capacitor of air medium.
