A particle is confined in the cubic box, each side computes 1 Angstrom. The mass of the particle is around10-30 kg. The potential energy within the box is zero; outside the box it is infinite.
Employ the Heisenberg uncertainty principle to determine the lowest possible momentum for the particle and compute the lowest possible energy for this particle in eV.
Determine de Broglie’s wavelength corresponding to the lowest possible momentum?
