Like.
I agree, the positive and negative charges depicted do not match the stated charge distribution. The diagram is tricky to interpret... -
JJesseAbberton reacted to PhDeezNutz's post in the thread Field at a point on the axis of a ring with variable charge density with Like.
I think it's obvious that the far field approximation should be that of a dipole from the picture shown. That diagram is confusing. It...

JJesseAbberton reacted to kuruman's post in the thread Field at a point on the axis of a ring with variable charge density with Like.
First of all, the charge density is given as ##\lambda(\phi)=\lambda_0\cos(\phi)## where ##\phi## is the azimuthal angle as shown in the...

JJesseAbberton reacted to TSny's post in the thread Field at a point on the axis of a ring with variable charge density with Like.
Refer to: Note that ##\phi## is measured from the ##z##-axis. So, all elements of the ring with positive ##z## coordinate should be...

JJesseAbberton reacted to kuruman's post in the thread Field at a point on the axis of a ring with variable charge density with Like.
Sure, I agree that the drawing has mislabeled the positive and negative arcs on the ring, but how does that affect the integrals' setup...

JJesseAbberton replied to the thread Field at a point on the axis of a ring with variable charge density.I just needed help with this part. I felt that the diagram was wrong and hence I got a "wrong" answer (according to the textbook). I did...

JJesseAbberton replied to the thread Field at a point on the axis of a ring with variable charge density.Since it's a ## \cos(x) ## function, so according to the diagram, if they have chosen the following Azimuthal angles, then positive...

Looks good.
