Explanation / Answer

capacitance, C=2 mF

separation, d=5um

Teflon dielectric constant, K=2.1

a)

use,

C=K*eo*A/d

2*10^-3=2.1*8.85*10^-12*A/(5*10^-6)

===> Area, A=538.07 m^2

b)

let,

electric field between the palte is E

then,

voltage, V=E*d

V=E*(5*10^-6) volt

c)

charge, q=C*V

q=2*10^-3*(E*(5*10^-6)

=E*(1*10^-18) C

D)

Volume, V=A*d

=538.07*5*10^-6

=2.69*10^-3 m^3
