So in this problem, we know that to the energy of the electron. Yes, 100. Que electra bolts. So I suppose this is doing the normal normal domestic limit. And we have e equal p squared over two m. Right? Soapy is the moment, um, off this electoral and a massive massive electoral, which is an important one times 10 to the native, 31 kilograms. So you can store. Even so, for the, uh, pee standing up to the people 1.21 times 10 to the negative 22 kilograms meters a second. So the wave lands of this electron equal h overpay. So this gives you 3.89 times 10 to the native, three nanometers.
