39. The capacitance is given by
C
=
κC
0
=
κε
0
A/d
,where
C
0
is the capacitance without the dielectric,
κ
is the dielectric constant,
A
is the plate area, and
d
is the plate separation. The electric feld between
the plates is given by
E
=
V/d
,where
V
is the potential diFerence between the plates. Thus,
d
=
V/E
and
C
=
