A square surface of side L meters is in the plane of the paper. A uniform electric field E (volts/m), also in the plane of paper, is limited only to lower half of the square as shown in the diagram. What will be the electric flux (in SI units) associated with the surface.
Answers
Answer : 0
In this example, electric lines are passing parallel to the surface of paper.
For electric flux to generate, electric lines needs to pass through the paper which is not happening in this example.
Here the area where electric lines are passing does not matter, since it is parallel to paper.
Based on above justifications, electric flux (in SI units) associated with the surface will be 0.
Answer:
The answer would be zero
Explanation:
the area vector of the square side is perpendicular to its plane.
since here the electric field is with the plane of square surface,the angle between E and A will be 90
cos90=0 and hence electric field is zero
it doesnt matter whether the electric field is only in the limited region or through the whole surface.what matters is the angle between E and A in any case
