Physics 36 The Electric Field (1 of 18)

The electric field, charges, forces, accelerating particles, there's so much to cover and it's all so much fun! In this four part lecture series I'll introduce you to the principles used to accelerate atoms to 99.9% the speed of light in the LHC.

First of all, the elessons are amazing and very helpful, thanks for that. Secondly I have a question about the problem. I didn't understand how did you find the magnitude of the small electrion that added in the electric field later on the question? How did it get the value of -1.6x10^-19? Did you made it up or is there a solid solution to find the value of it? Thanks...

thanks teacher but wheres the main lessons?

[johnstillman]

seems like good educational videos its a pity there's no volume

[tyroneslothdrop]

The amount of content on your channel is simply astounding, and you show no signs of slowing down.  You're a legend in my book.

Monica,
The charge on an electron was experimentally discovered by Millikan utilizing his oil drop experiment.
(I have a video on that)

[MichelvanBiezen]

"mu" which stands for "micro" = 1 x 10^-6
So 12 microcoulombs = 12 x 10^-6

[alitabrizi]

He is truly one of the best teachers in here....

[HoracioMiguelGomez]

It's missing the direction of the acceleration, it only solved the magnitude. Should put -1.6x10.... with the minus and also the (x versor) so the final answer has a (-x^)

[Sofialovesmath]

Your explanations are amazing, finding this channel has been one of the best things for my degree.

[poincareconjecture]

Sir you make very abstract subject matter so easy and straight forward to understand and the genius of that can almost be under appreciated; what you do is not as easy as people think! You are a great public servant i really hope you can consider doing interviews on radio CSPAN, NPR, BBC...your such a talent thank you again!!!YOU TUBE DESERVES TO PAY YOU!!! C'mon Sergei do the right thing!!!

[winterraven]

passed my physics exams because of your videos, I owe you my life sir thank you lol

[tarabiqbal]

Greetings from Qatar!
A very helpful video, sir. :)

[jamgamer]

This helped me put things in perspective better much better than my physics professor. Thank you

[zaceriah]

Your content is great and I’m learning more than ever - I’m also watching your general relativity series, thanks you so much!

[Lily-kwoc]

Thank you so much for these amazing explanations. You help me a lot. I couldn’t find as useful videos in this topic in my own language as yours. I’m so grateful, you are an amazing teacher!

AHA!! .. I answered my own question before asking it here... I was going to ask you if we could use Coulomb's formula, F=(kQq)/r^2, to find the FORCE and then insert that into the .. a= f/m equation.. rather than using the F = E/q... .. well.. as you know... IT DOES WORK... lol .. but this problem was centered around the Electric Field concept... so I see it was easier to go that route... I guess it was just nice to see the Consistency in using various FORCE Equations and they all work out fine... Thanks Michel for another great series of Video Lectures.... interesting to note that if F=E/q and F = (kQq)/r^2 then E/q = (kQq)r^2 .. or multiplying both sides by q .. gives an equation for E = (kQq^2)/r^2 .. interesting.. just multiplying Coulomb's Equation by the charge "q" yields the Electric Field, E ... or as EINSTEIN would say, "Gee, Whodda Thunk It?!"

6:28 I like how you acted like you had to "try" to remember the mass of an electron lol

[gregoryappiah_mensah]

thanks very much sir for your impact. you have made physics look more understanding for i and my friends. we love you and God bless you and all those sponsoring you if there is any. KEEP IT UP.

[Pandacuddless]

When calculating the acceleration of the electron force, how come we don't put the force as negative?

[DENNISKIPKOECH-kj]

are we ignoring the electric field caused by electron?
BIG THANK YOU PROFESSOR
