Electric Field from a Ring and a Disk

Physics Ninja looks at the problem of calculating the electric field from a ring and disk by integration. The ring and the disk are uniformly charged the field is calculated for a point on the axis.

Once you said it took you a while to get this, i knew i was at the right place. Cos people like you know how to explain it in the simplest of terms since you have been in our position before. Thank you. DOn't stop what your're doing

[@affection231]

sir you ended my nightmare about these topics. Best of luck for you and your family in the New Year 🎁🎀🎄🎄

[@noctao4163]

I liked how well this was explained I just started learning about this and it helps a lot.

[@PhysicsNinja]

Thank you!

i was your 420th like, youre welcome....
also thank yoooou, these vids are the bees earlobes

[@jojoo_aah8072]

Omg, the best explanation i had see so far!

[@godisgood2482]

Are there any experiments video showing electric field due to ring? And is the ring always going to get uniformly charged if we try to charge it

[@vaibhavgowda6725]

If the ring is perfectly conducting/metallic then yes it will have uniform charge distribution regardless of how we charged it. Unfortunately I couldn’t find any videos showing field due to a ring irl.

Doesn't x change depending on the distance of the point we're choosing to calculate the electric filed for?

[@lucassarappa3327]

Hello friend, the video is very good, but I have a question with a similar exercise:
I need to find the electric field at a known midpoint of 2 charged circular loops like the ones in the video (each with a different charge, both positive).
I have to apply the formula that you show in the video for each of the circular loops, and then my question is:
Should I add or subtract each of the results to obtain the electric field at that point? (taking into account that both charges are positive). Thank you so much

[@mohammedhisham7443]

How did you modify the new limits?, any video or explanation on that.

Which type of gussian surface we will take in order to find E field due to a hollow capsule like object which have both hemisphere and cylindrical symmetry?

[@LilLefty27]

why is your point source formula kQ/r^2 instead of kQ/r? I have conflicting info in my notes from class

[@PhysicsNinja]

Kq/r2 is electric field and kq/r is electrical potential, not the same

Thank you sir

[@chathunikulathunga3039]

Thanks man

[@miguelbuitrago6050]

Is it possible find that Electric Field using the electric field of a line?

[@adwardwilson1857]

the ring is finite, but for calculate the electric field of a finite line we have to use the gauss law

Wow

[@kabokbl2412]

Had a bad day due to this topic evicirating me in a quiz

[@erickcastellanos6814]

huh.
