Question

A system of two parallel plates, each of area A, are separated
by distances d₁ and d₂. The space between them is filled
with dielectrics of permittivities ℰ₁ and ℰ₂. The permittivity
of free space is ℰ₀. The equivalent capacitance of the system
is
(a) ℰ₁ℰ₂A/ℰ₂d₁+ℰ₁d₂
(b) ℰ₁ℰ₂ℰ₀A/ℰ₁d₁+ℰ₂d₂
(c) ℰ₀A/ℰ₁d₁+ℰ₂d₂
(d) ℰ₀A/ℰ₁d₂+ℰ₂d₁
