An electric field is applied on a copper plate such that the electrons are displaced by \(1.1 \times 10^{-18}\,\text{m}\) relative to the nucleus. The electronic polarization (in \(\mu C \, m^{-2}\)) is (rounded off to two decimal places).
Given: Atomic number of copper = 29,
Copper has FCC crystal structure with lattice parameter = 0.362 nm,
Electron charge = \(1.6 \times 10^{-19}\, \text{C}\).
