The x coordinate of an electron is measured with an uncertainty of 0.20 . 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 1.0 %% ? Use the following expression for the uncertainty principle: ΔxΔpx≥h2ΔxΔpx≥h2, 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 hh is Planck's constant.
