Application +4 | -1
The extent of localisation of a particle is determined roughly by its de Broglie wavelength. If an electron is localized within the nucleus (of size about 10−14 m10^{-14} \mathrm{~m}) of an atom, what is its energy?
View answer and explanation
Correct option: A
124.3 MeV124.3 \mathrm{~MeV}
