A paper-filled capacitor is charged to a potential difference of

V_(0)=2.4V

. The dielectric constant of paper is

\kappa =3.7

. The capacitor is then disconnected from the charging circuit and the paper filling is withdrawn, allowing air to fill the gap terween the plates. Find the new potential difference

V_(1)

of the capacitor. While the capacitor is disconnected from the charging circuit, an unknown substance is inserted between the plates. The plates then attain a potential difference that is 0.67 times the original potential difference

V_(0)

(when paper filled the capacitor). What is this unknown substance's dielectric constant

\kappa _(u)

?

K_(u)=
