Physics 36 The Electric Field (9 of 18) Disc of Charge

In this video I will find the electric field of a disc of charge.

my professor doesn't have your level fluidity and confidence with the material, so you can bet this video is helping! thanks from Montreal, Canada

[stevesadler]

This is a godsend. Our professor skipped justification of every step, and without this I would have to just memorize his proof rather than understand it

[lderz]

amazing! I cannot thank you enough. I was so lost and confused with this until I saw this video.

[lofijedi]

thank you for all that you do. You make physics easier to understand and i appreciate the hard work you've put into this channel. Its appreciated.

[SeanGhaeli]

big ups! First time I'm integrating multiple variables so its getting tangled in my head but you're making it clear!

[CatsBirds]

You are the best! Probably got tired by hearing that from me and others who love your teaching.

[valeriereid]

Excellent! I understand this so much better on second viewing. Thanks for for all your excellent lectures we appreciate them.

[pizzadeliverygurl]

You're really good at explaining the concepts thanks so much for posting!

[Dklcşşslfl]

I feel obligor to support your channel, at least by typing comments and liking videos because you share this legends with us for free

[billypentester]

I like this teacher because he learns effectively! Thanks!

[apexiaditya]

Thanks from India a Jee advanced aspirant this is very helpful in solving Advanced

[BoOiika]

excellent explanation, you sir are amazing 
THANK YOU!!

[Fiendnat]

i watched your videos when i was a junior in high school. Now i am a junior in college and you're still teaching me!

[ozgurgomlekli]

I don"t know how can i thank you. You are an awesome teacher.

[mariopersaud]

you have helped me a lot. i started watching your videos last semester and you're the best. I actually understand the lessons after I watch you explain them.
thank you
 

[valeriereid]

Thanks so much for showing all the steps, especially in this one which would have been very difficult without your help.

Hello, I was wondering why we don’t use use a double integral, instead integrating dE over 0 to R then 0 to 2pi.

[lillllooooo]

Can you please explain why you're using the area of a circle for the ringlet for A in dA? Shouldn't it be the outer radius - the inner radius since the shape is not a circle?

[suheda]

hi sir, firstly i wanna thank you so much. i have a question: what if a>>R0? right side of the last formulation becomes zero, so does that mean that the disk doesn't act like a point charge?

[lefterisspanoudakis]

How can we prove in that case using math, and not symmetry on the ringlet, that the vertical components are add up to zero?
