Consider an electron in front of metallic surface at a distance d (treated as an infinite plane surface). Assume the force of attraction by the plate is given as \(\frac{1}{4} \frac{q^{2}}{4 \pi \varepsilon_{0} d^{2}}\). Taking d = 0.1 nm, find the work done in eV in taking the electron to an infinite distance from the plate. [Such a force law is not valid for d < 0.1 nm].
