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

Part A

Determine the capacitance if $K_1=1,K_2=3,$ the area of the plates $A=5m{m}^2,$ 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 $8\mathrm{.}85{10}^{-12}F{m}^{-1}$

$C={?}^{p}F$
