So in this problem we know that the velocity of the electron is 3% off the speed of lights. So we want to figure out the deploy with blends off this electron. So from your textbook, we see the formula Lunda, which is the weapons off this electoral equal. H overpay soapy is the mo mentum. So because the velocity here, it's actually not so large. It's not very close to ah the sea. So basically, we can utilize that non relativistic formula Soapy has forming and pens be right. So m is the mass of electron, which is number one times 10 to the negative, 31 kilograms and ah ah, you can do the calculation straightforward. And you can see that final solution is 8.1 times 10 to the ***, too. Uh, nano meters. Okay.
