The x coordinate of an electron is measured with an uncertainty of 0.200 mmmm . What is vxvxv_x, the x component of the electron's velocity, if the minimum percentage uncertainty in a simultaneous measurement of vxvxv_x is 1.00 %% ? Use the following expression for the uncertainty principle:

ΔxΔpx≥ℏΔxΔpx≥ℏ,

where ΔxΔx is the uncertainty in the x coordinate of a particle, ΔpxΔpx is the particle's uncertainty in the x component of momentum, and ℏ=h2πℏ=h2π, where hh is Planck's constant.

Use the Heisenberg uncertainty principle to estimate the uncertainty in momentum resulting from confining an electron to an atom (~10-10 m) and to the size of an atomic nucleus (~10-15 m). Calculate the corresponding uncertainty in the energy (in eV) of the confined electron and briefly comment on the physical implications of your results.
