I wanna know that how the angle becomes "0" degrees; when electric field lines passes through a given surface (given in the image). I think it should be "90" degrees!
It is a question of Electric Flux. [File Attached.]

k!

maheshmeghwal9 · Answer

now what should I do with my question?

maheshmeghwal9 · Answer

I am asking why the angle is 0 degree

anonymous · Answer

Because the area vector and the field lines are both parallel to the plane, and are thus perpendicular

maheshmeghwal9 · Answer

so we measure angle on the basis of position of area & electric field vector?

anonymous · Answer

exchange || and perp

anonymous · Answer

what r u saying?

anonymous · Answer

the area vector has a direction perp to surface/// in this case angle theta is angle bw area vector and field lines

maheshmeghwal9 · Answer

ya I also meant to ask that point which u now told. Thanx a lot:)

no probs mate
