Part A 

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