Answer 1

Capacitance of parallel plate capacitor, C = ($\epsilon _{o}$$\times$A)/d

where $\epsilon _{o}$ is permittivity of free space, A is area of plates and d is distance between plates

C = 8.85 $\times$ 10-12 $\times$ 100 $\times$ 10-4 / (0.25 $\times$ 10-3 ) = 35.4 $\times$ 10-11 F = 0.354 nF
