Birdy · Answer 1

1/8 x C

Explanation:

The capacitance of parallel plate capacitor

= ε₀ A / d where A is area of plate and d is distance between plate.

for capacitor 1

C = ε₀ A / d

For capacitor 2

radius = R/2

Area = A / 4

Capacitance

= ε₀ (A/4) x (1 / 2d)

= (1 / 8) x (ε₀ A / d)

= 1/8 x C
