1) An electron is confined to a square box of length L, and the walls of that box are infinitely high. The zero-point energy (ZPE) is defined as the minimal energy that corresponds to the smallest quantum number n. What would be the length of the box L such that the ZPE of the electron located inside this box is equal to its rest mass energy mc?

1) An electron is confined to a square box of length L, and the
walls of that box are infinitely high. The zero-point energy
(ZPE) is defined as the minimal energy that corresponds to
the smallest quantum number n.
What would be the length of the box L such that the ZPE of the
electron located inside this box is equal to its rest mass energy
m.c²?
