Question

A parallel plate capacitor has plate area 40cm² and plates separation 2 mm. The space between the plates is filled with a dielectric medium of a thickness 1 mm and dielectric constant 5. The capacitance of the system is

(1) 24ε₀ F

(2) 3/10 ε₀ F

(3) 10/3 ε₀ F

(4) 10ε₀ F

Answer 1

Correct option is (3) 10/3 ε₀ F

This can be seen as two capacitors in series combination so
