Between the plates of a parallel plate condenser, a plate of thickness ${t_1}$ and dielectric constant ${k_1}$ is placed. In the rest of the space, there is another plate of thickness ${t_2}$ and dielectric constant ${k_2}$. The potential difference across the condenser will be

  • A

    $\frac{Q}{{A{\varepsilon _0}}}\left( {\frac{{{t_1}}}{{{k_1}}} + \frac{{{t_2}}}{{{k_2}}}} \right)$

  • B

    $\frac{{{\varepsilon _0}Q}}{A}\left( {\frac{{{t_1}}}{{{k_1}}} + \frac{{{t_2}}}{{{k_2}}}} \right)$

  • C

    $\frac{Q}{{A{\varepsilon _0}}}\left( {\frac{{{k_1}}}{{{t_1}}} + \frac{{{k_2}}}{{{t_2}}}} \right)$

  • D

    $\frac{{{\varepsilon _0}Q}}{A}({k_1}{t_1} + {k_2}{t_2})$
