The area of the plates of a parallel plate condenser is $A$ and the distance between the plates is $10\,mm$. There are two dielectric sheets in it, one of dielectric constant $10$ and thickness $6\,mm$ and the other of dielectric constant $5$ and thickness $4\,mm$. The capacity of the condenser is
  • A$\frac{{12}}{{35}}{\varepsilon _0}A$
  • B$\frac{2}{3}{\varepsilon _0}A$
  • C$\frac{{5000}}{7}{\varepsilon _0}A$
  • D$1500\;{\varepsilon _0}A$
