Two different dielectrics each fill half the space between the plates of a parallel$-$plate capacitor as shown in $($Figure $1).$

Part A

Determine the capacitance if $K_1=1\mathrm{.}4,K_2=2\mathrm{.}4,$ the area of the plates $A=10m{m}^2,$ and the separation $d$ is $2$ mm $.[$Hint$.$ Can you consider this capacitor as two capacitors in series or in parallel?$]$

Take the dielectric constant $lo{n}_0$ as $8\mathrm{.}85{10}^{-12}F{m}^{-1}$
