Aat 60 degrees to the field
Bat 45 degrees to the field
Cparallel to the field
Dperpendicular to the field
Answer & Solution
Correct answer: C. parallel to the field
Flux = E A cos(theta) with theta measured from the area vector; a surface parallel to E has theta = 90 degrees so no lines pass through it.
