Suppose that free charges are present in a material of dielectric constant

ϵ = 10

and resistivity

ρ = 10^{11} Ω - m

. Using Ohm's law and the equation of continuity for charge, the time required for the charge density inside the material to decay by

1/ e

is closest to

1 $10^{- 6} s$
2 $10^{6} s$
3 $10^{12} s$
410 s
