At equilibrium there can not be any free charge inside a metal. However if you forcibly put charge in the interior then it takes some finite time disappear move to the surface. If the conductivity σ of au metal is 106 (Ωm) −1 and the dielectric constant  8.85 × 10−12 Farad/m, this time will be approximately?

Introduction:
At equilibrium, there is no free charge inside a metal. However, if charge is forcibly placed inside the metal, it takes some time for the charge to move to the surface and disappear. In this scenario, we are given the conductivity (σ) of gold (Au) and the dielectric constant (ε) to determine the time it takes for the charge to move to the surface.

Formula:
The equation that relates the time it takes for the charge to move to the surface (τ) with the conductivity (σ) and the dielectric constant (ε) is given by:
τ = ε / σ

Given:
Conductivity (σ) of Au metal = 10^6 Ωm^(-1)
Dielectric constant (ε) = 8.85 × 10^(-12) Farad/m

Calculation:
Using the given formula, we can calculate the time it takes for the charge to move to the surface.

τ = ε / σ
= (8.85 × 10^(-12) Farad/m) / (10^6 Ωm^(-1))

Simplifying the expression, we can convert Farad/m to Ωm^(-1) by taking the reciprocal:

τ = (8.85 × 10^(-12) Farad/m) × (1 Ωm / 10^(-6) Farad)
= 8.85 × 10^(-6) s

Answer:
The time it takes for the charge to move to the surface is approximately 8.85 × 10^(-6) seconds.
