So in this problem, the energy of the electron is that the electrons accelerated in the in the potential difference off 30 kilovolts. In that case, the energy over the electron is, uh, 30 key 30 k electro volts. OK, so this equal peace quit over to m were appease the moment, um, off the electron and m is the mass of the electron, and they go see, That's ah, so mass. Here is the 9.1 times 10 to the negative. 31 kilograms. Okay. And ah, you can see that. Ah ah, the against. So for the moment, um, of this electron, you can say that this video is 9.35 times 10 to the negative. 27 kiddo. Run made up a second. Yeah. So we done so for the weapons of this electron, which is hte overpay. So this gives you Ah, 7.1 times 10 to the native. Three nano meters. Yeah,
