A parallel-plate capacitor consists of two parallel, square plates that have dimensions 1.0cm by 1.0cm. If the plates are seperated by 1.0mm, and the space between them is filled with teflon, what is the capacitance fo this capacitor? (the dielectric constant for teflon is 2.1, and E0 = 8.85 x 10⁻¹²C²/Nm²
a). 1.9pF
b). 89pF
c). 2.1pF
d). 44pF
