Chemistry

The x coordinate of an electron is measured with anuncertainty of 0.200 mmmm . What is vxvxv_x, the xcomponent of the electron's velocity, if the minimum percentageuncertainty 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 aparticle, ΔpxΔpx is the particle's uncertainty in the xcomponent of momentum, and ℏ=h2πℏ=h2π, where hh is Planck'sconstant.
