Doesnt the electric field due to a line charge depend on the distance from the line? Seems like the answer should depend on the height above the sheet.

Good question. In my case it’s just a side view of a plane which look like a line but it’s still a plane characterized with a surface charge density. You are right that for a line the field depends on distance from the wire.

Thank you so much for your explanation. It is very clear, however, which I don't understand in the second example (two oppositely charged plate): The total electric field is E1 + E2, with E=sigma/2Eo. BUT isnt sigma of the second electric field negative and so if we did the sum of them, it would equal to zero ? I hope I make myself clear.. I see that we only make the sum of the magnitude.. but I don't understand why we don't respect the polarity of the charge density. Any help would be greatly appreciated :) thank you so much!

Sigma is negative but both field point in the same direction. Fields must be added together as vectors. Field point away from positive charges and towards negative charges

Sir why whole charge on the sheet is not included in cylindrical gaussian figure just a part of sheet , the formula is (total charge enclosed/epsilon)

No its charge enclosed in the surface

@@PhysicsNinja ohh that means the non included sheet in the cylinder has no effect on our required answer?
