The x coordinate of an electron is measured with an uncertainty of 0.200 mm. What is Vz, the x component of the electron's velocity, if the minimum percentage uncertainty in a simultaneous measurement of v, is 1.00 % ? Use the following
expression for the uncertainty principle:
AcAp.
where h is Planck's constant.
where Az is the uncertainty in the x coordinate of a particle, Apz is the particle's uncertainty in the x component of momentum, and ħ=
