39. The capacitance is given by C = κC0 = κε0 A/d ,where C0 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 = κε
