An electron is accelerated by a constant electric field of magnitude 300 $\mathrm{N} / \mathrm{C}$ . (a) Find the acceleration of the electron. (b) Use the equations of motion with constant acceleration to find the electron's speed after $1.00 \times 10^{-4} \mathrm{s}$ , assuming it starts from rest.

a. $5.27 \times 10^{13} \mathrm{m} / \mathrm{s}^{2}$

b. $5.27 \times 10^{5} \mathrm{m} / \mathrm{s}$

Hala Strange. Let's start our discussion. Suppose electron is a saluted bile electric field off magnitude 300 Newton or Coolum. Now you have to find out the magnitude off that laceration. Basically, force will be Kui on that particular electric and this forces according to mass in tow. Aspiration. So basically from here, aspirational comes out to be a q e buy em. This is the mass off the electric. Okay, And this is a charge on the electron. So it will be 1.6 into 10 this par minus 19 Coolum and 300 Newtons for Coolum by 9.1 in took 10 days by minus 31 kg. If you saw this, you will get the value off 5.27 into 10. Respond 13 meter per second square. This is the amount off a celebration that is done by the electric field. Okay, Now supposed you have to find out the speed off that electron at time. Daisy goes to one in Took 10. This bomb scare second, with this acceleration and the initial speed initial velocity off that electron is Jiro. So basically we have they questioned basic wish to you plus Haiti. So initial velocity jail. So you will be Jiro. Raise questo gentle plus 5.27 into 10 days. Part Orting in tow. One in tow. Temptress by minus eight second. And that will comes out to be 5.27 in took 10 this par five meter per second. This is the velocity of the electron speed off the electron at Time T equals to one in tow. 10 this part minus their second. Well, this is all for me for this video. I hope you will like the video. Thank you.
