A flat circle of radius 17 cm is placed in a uniform electric field of magnitude 6.2 102 N/C.
(a) What is the electric flux through the circle when its face is perpendicular to the field lines?
______________________N·m2/C
(b) What is the electric flux through the circle when its face is at 50° to the field lines?
______________________ N·m2/C
(c) What is the electric flux through the circle when its face is parallel to the field lines?
______________________ N·m2/C
