Question

The picture shows a circle, viewed nearly edge-on, sitting in an electric field.  The electric field is 30°from the normal to the area (bold arrow) and 60° from the surface of the circle (dotted line is in the plane of the circle.)  

30° 60%

A. If the circle has a diameter of 12 cm, and the electric field has a strength of 8.1x10³N/C, what is the electric flux through the circle?  [79.3 Nm²/C]

B. Assuming you can change the orientation of the loop (spin it, change the angles), how could you get no flux through the loop? Sketch this arrangement.

C. Assuming you can change the orientation of the loop (spin it, change the angles), how could you get the most flux through the loop for the given electric field? Sketch this arrangement, and calculate that flux.
