i tried to apply uncertainty principle to an electron confined in a 3d box of size 1fm.(adsbygoogle = window.adsbygoogle || []).push({});

i got uncertainty in velocity Δv to be of the order 10^{10}m/sec.so i thought maybe i should have taken relativistic mass instead of rest mass.

but i realised that for calculating relativistic mass we need to know the velocity of the particle.but since we dont know that,

i was wondering whether we could ascertain whether its possible for electron to be confined in a 3d box of that size?
