(a) If the position of an electron in a membrane is measured to an accuracy of 1.00$\mu \mathrm{m}$ , what is the electron's minimum uncertainty in velocity? If the electron has this velocity, what is its kinetic energy in eV? (c) What are the implications of this energy, comparing it to typical molecular binding energies?

a) 57.9 $\mathrm{m} / \mathrm{s}$b) $9.52 \times 10^{-9} \mathrm{eV}$c) This kinetic energy of the electron is approximately 9 orders of magnitude smaller than typical molecular binding energies.

So in this problem, we know that Ah, the the position uncertainty off the electron that ax as one like a meter. And, uh, according to the head Zinberg uncertain in law, we have expression down acts that a p times that if he is greater or equal to H over full pie. So here we only use the equal case. Okay, so we can see that that would be equal, H D Bye bye. Full pie times that x ray and ah, you have to know that that key here equal 5.28 times 10 to the 29th kilogram meters per second and the devil p equal m times that of the right so that he's the change of the velocity so cramped in the dead of equal. Ah, 58 made up a second. All right, so this is the velocity uncertainty of this electoral. So this part A and in part b suppose the electron has this Ah, has this much of ah velocity Want to know that kind of energy on this so equal half and times that of the squid, right? So we can simply get the solution. So this is nine point 56 times 10 to the *** knives, electro volts and in part, see Ah. So typically the bunny energy off the mod accuse arranges around wind travels to take electro volts and clarity. This one is much smaller than the money energy of the monarchy.
