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

deltaX * deltaPX >= h2,

where deltaX is the uncertainty in the x coordinate of a particle, deltaPX is the particle's uncertainty in the x component of momentum, and h is Planck's constant.
