(1) How much work is required to stop an electron $\left( m = 9.11 \times 10 ^ { - 31 } \mathrm { kg } \right)$ which is moving with a speed of $1.40 \times 10 ^ { 6 } \mathrm { m } / \mathrm { s } ?$

Has the first kinetic energy This equation twenty six Dash five is equal the gamma minus one times Rasmus and years he square. Or so when this thing K equals a saying, M C squared means that kicky of M C squared, which you can see from this equation is government's. One will be equal to one, and so gamma will be, too. And the definition of gamma we know that is one over square of one minus V squared over C square, so so you can square about sides. Is that for it's one over one minus P squared C square? Yes, you three. It is quite eight six, six seats, six, six times the speed of light. And then momentum is from creation twenty six dash for the book. It's just gather on times. Empty cameras, too. M is so em is given as that. So it is given us nine eleven kilograms a nine point eleven times. They're late of thirty one kilograms, but we know on electrons rest mass energy is point five one one m e p. So we just divide that by C squared and that's our mass. We don't have to worry about kilograms and converting you Teo meters per second. So your V ous point eight six six times, see? And so you get a nice answer in terms of any of you ever see, which is point eight eight seven he oversees, and that's it.

12. For the given problem, we have one minus we square divided by C square. All right, root is equal to one divided by two. So taking square on both sides one minus B squared, divided by C squared is equal to one divided by four and solving for really easy home to wrote three divided by two times the speed of light, therefore really is equal to zero point in 66 times the speed of light.

Here. In this question, Moss is given massive collect on how much? Nine point 11 in two tend to the power minus 31. Gigi. And initially, spirit is given we I is equal to 1.10 into 10 to the power six meter per second since electron is finally stopped. So we final that is Finally speed is equal to 0 m per second. Here, we can apply work. Kind of take an object here. Um so apply work unless Project Kind knittig? Yes, one, it's and energy. Okay. Yeah. Tell them according to work. Kinetic energy Terram work is equal to change in kinetic energy and change in kinetic energy means final, kinetic energy minus initial kind of technology. So work is equal to half m. Yeah, Worthy, are you? We final Squire minus half. Mm. We initial Squire. So now if we substitute the values, then since we finally zero So this part will become zero minus have mass off electron 9.11 Improved 10 to the power minus 31. And initially speed is 1.10 in two. Tend to the power six Squire. And this we will get in Jewell. So if we solve this expression, what we are getting is minus five point. What is due? 51 in two, 10 to the power minus 19. You. So this is the final answer. That is the work done to stop the Electra. Okay, these this is final. Funny thing. Yeah, so thank you. Yeah. On B B? Yes.

Here. The question is, if you understand this question, how much work is required to stop an electron having must this which is moving with a speed off 1.10 in tow, 10 to the power 6 m per second If we draw situation here. So this is electron, which is moving web initially speed 1.10 in two. 10 to the power 6 m per second and mass off. Electron is given 9.11 in tow, 10 to the power minus 31 K g. And finally this electron is coming to rest. So finally, speed, we can say it is zero. So now it is asking how much work is required. We stop this electron which is moving with this a spirit and having must this so we can apply work Kinetic energy, Terram. So apply work Dietetic energy Here. Um, according to this Terram work is equal toe change in kinetic energy. And we know the meaning off change that its final minus initial right, So we can Well, right here. Final kinetic energy minus kinetic initial kinetic energy. So final kinetic energy kinetic energy formalize happened we Squire. So if we apply this formula here, it will become half and we finally Squire miners have em. We initially square now we need to put the values here so we finally is equal to zero. So if we apply here, it will become zero minus Ah Massa off electron is 9.11 into 10 to the power minus 31 Into the initial is 1.10 in tow, 10 to the power plus six Squire. So it is a simple expression. We can solve it and after solving, we are getting minus 5.51 in tow 10 to the power minus 19 jewels. So work is asked So this is the final work which is required to stop the electron. So this is the final onset. I hope you enjoyed the solution.
