The figure below shows a parallel plate capacitor of plate area
A = 12.5 cm² and plate separation 2d =
7.93 mm. The left half of the gap is filled with material of
dielectric constant κ₁ = 21.0; the top of the
right half is filled with material of dielectric constant
κ₂ = 42.0; the bottom of the right half is
filled with material of dielectric constant κ₃
= 58.0. What is the capacitance?
