Two identical capacitors $1$ and $2$ are connected in series. The capacitor $2$ contains a dielectric slab of constant $K$ as shown. They are connected to a battery of emf $V_0\ volts$ . The dielectric slab is then removed. Let $Q_1$ and $Q_2$ be the charge stored in the capacitors before removing the slab and $Q'_1$ , and $Q'_2$ be the values after removing the slab. Then

  • A

    $\frac{{Q{'_1}}}{{{Q_1}}} = \left( {\frac{{K + 1}}{K}} \right)$

  • B

    $\frac{{Q{'_2}}}{{{Q_2}}} = \frac{{\left( {K + 1} \right)}}{2}$

  • C

    $\frac{{Q{'_2}}}{{{Q_2}}} = \frac{{K + 1}}{{2K}}$

  • D

    $\frac{{Q{'_1}}}{{{Q_1}}} = \frac{K}{2}$
