Question
(a) If the position of a chlorine ion in a membrane is measured to an accuracy of 1.00 μm , what is its minimum uncertainty in velocity, given its mass is $5.86 \times 10^{-26} \textrm{ kg}$ (b) If the ion has this velocity, what is its kinetic energy in eV, and how does this compare with typical molecular binding energies?
1. $9.00 \times 10^{-4} \textrm{ m/s}$
2. $1.48 \times 10^{-13} \textrm{ eV}$. The kinetic energy of the chloride ion is many orders of magnitude less than typical molecular binding energies.
