at 15:39 when you moved the x out in front of the integral, shouldn't it be a 1/x since it was in the denominator?

He corrected it after that already

[@modbus9600]

I'm confused about this part too😂

[@nehasinghbaghel9072]

Because it is treated as a constant and we are integrating with respect to theta that,s why he moved it out as a constant

At 7:08 how he got the equation for dEx was by understanding that x/r is proportional to dEx/ dE. Therefor: dEx/dE = x/r dEx/dE = cos(theta) dEx = dE (cos(theta))

quick question, at 16:52 when he sub dy and y values in integral, shouldn't his limits also change? why did he not write the limits for integral, x integrate cos(theta) d(theta)

I'm probably too late but his original limits were in terms of y, so no they do not need to change

very important formula to calculate electric field on a distance to calculate electromagnetic wave which is an antenna communication

God bless you for this explanation

[@DANIELJOHNSPARDENILLA]

15:38 shouldn't it be 1/x in front of the integration symbol, not x?

[@Down2HellBBX]

Hey can you also take up the case where the point of observation (that is where we are supposed to find out the electric field) is not symmetrically placed , like what happens when the Y-component does not cancel out???

[@shdhong]

I believe that your comment (more of a question I believe) is very valid. To the best of understanding, the method shown only works for finding the electric field from a distance x from the center of the line charge. The y-components of the electric field for other points do not cancel as you pointed out. More complex integration is needed. In the numerical example near the end of the video, it asks specifically the electric field 80 cm away from the center of the rod.

[@vialvile107]

This is great! Could you please do one for a point that's not at the center?

[@sergiovavra5720]

That would be stupidly difficult homie leave that to the computers to compute

[@Me12222]

ik this comment is 3 years old and ur probably already an engineer that does this for breakfast, but in the video he explains how you can find Ex and Ey for a point not in the center using integration and then you can take the vector sum to find the field intensity vector

[@hvrkim5154]

your the best

[@IamKudos]

in 13:30, the derivative of y on the left hand side should be dy/dt but we just wrote it as the differential of y, dy. And then replaced it aswell in the integration. Am i missing something?

[@jamiecole5433]

pretty sure it's dy = xsec^2(θ) dθ (with respect to θ) , not just dy.

[@sanjanakerkar8255]

this is really helpful, thank you!

[@banzangayusa7380]

dear brother thank you very much for the work you have done to explain to us clearly j aime tes video

[@odgarig8601]

My professor never mentioned that point P next to the the middle of the line, so It was hard for me to get why Ey is 0

[@Slee-pcc]

(15:42) There is a mistake when solving for the integration..... you can't take out x but have to take out 1/x

[@神拜]

yes and he fixed the mistake in 17:44

[@williamscott6291]

Very nice, however I am struggling with the situation where the point P in not on the x axis. This means that the charged rod is not centered under P. The y components of E do not cancel and the x components are not symmetrical either. This is a much more difficult calculation and one that I have not seen anyone do. Could you extend this lesson to the more general case of an electric field at some point over any place of a charged line?

Please factorizing x out of the integral was suppose to be 1/x not x multiplied by the whole integral please I don't why you multiplied x to the whole integration to get x cos it would been 1/x cos please explain
