The y axis is also normal to the cylinder's axis... But I think I get it it also depends on where the reference point is...so

Okay I see, a point on the y axis (in my diagram) would also have field ## E_y ## a point the x and y plane would also have fields (## E_x##& ##E_y##) but a point on the cylinder's axis would not have any net field.

Yes I got that, the z axis is the cylinder's axis, the y axis is one of the two axes in the cross section of the cylinder... The above image is the reference axes I took. In the image below the person has taken the cylinder's axis as y axis and the axis whose field im confused about as z axis...

I know ive already been very slow in understanding but after reviewing everything i dont understand why Along the y-axis, there is no preferred direction. Any point on the positive y-axis is symmetrically not equivalent to its counterpart on the negative y-axis. Therefore, any electric field...

Also for the case of the cylinder equations appear to be symmetrical only about the axis of height...the plane in cross sectional area is where the direction of Electric field Should be ...

I see... In the case of cylinders theres this simplification which most standard textbooks use and they assume the charge of the cylinder to lie on an infinitely long rod...how do they get that?

If its symmetrical about an axis then that is Not a solution?

I think i get it.....Can you tell me how the cylinder case can also be viewed...how do I rotate the cylinder about the z axis ...?

Also for the cylinder case... Since the z axis is infinitely long considering the height is along the z axis... The x and y axis are on the cross sectional area of the cylinder... Any point inside the cylinder's net field would only be in the x and y direction? Net field could only be calculated...

This applies to a point inside as well as outside the slab?

Please check I have edited.... The little white mark is because my number was visible...learnt it the hard way that people on physics forums could also be concerned with prank calling numbers 😔

But if I take an individual element in the slab and use that to find a small de field at a point x and y component wont be zero right... The total sum of the x component and the total sum of the y component would be zero respectively... I think

But its a video in an app Which doesnt allow screenshots or screen recordings...I could use another device to take a snapshot hmm uploading now..

So that just means if I integrate the small de fields acting on a point inside the slab (not on the surfaces) throughout the whole volume...id get only the z component as the net field... The x and the y components would be same on either side of this point... Hence they would cancel out?
