Help Needed: Understanding Gauss's Law and Electric Field

[eRa]

Hi there,

I have a question for you guys. It might sound stupid, but I don't get the material; my teacher can't teach! and your help is very appreciated

I am reading about Gauss's law where they come to the conclusion that flux=charge/Eo

as in this link http://hyperphysics.phy-astr.gsu.edu/HBASE/electric/elesph.html

my question is why won't the net electric field be zero since we can cancel the field lines?

Thanks in advance

we can cancel the field lines?

With what?

Why won't the net electric field of what be zero? What field lines are canceling?

(That link describes the field from a point charge.)

hi.. sorry I didn't mean to be unclear

True ,, the link describes the field from a point charge so each field line has another field line that is in the opposite direction.. so why don't all the field lines cancel?
I am sorry I don't know how to explain it better

Flux is through a surface …

all the field lines in the diagram are going the same way through that surface.
