A loop of diameter 21 cm is placed in a uniform electric field of magnitude 7.4 102 N/C.
(a) What is the electric flux through the loop when the electric field is perpendicular to the plane of the loop? N·m2/C
(b) What is the electric flux through the loop when the electric field is 45° from the plane of the loop? N·m2/C
(c) What is the electric flux through the loop when the electric field is parallel to the plane of the loop? N·m2/C
