At every location on the surface the electric field points in the same direction (+y). E 1 is found to be 540 V/m; E 2 is 780 V/m; E 3 is 1212 V/m. (a) Which of the following statements are true? (b) What is the net electric flux on this surface? net electric flux = -3.377 -3.38 Vm Vm Ch22 HW2 F2010 (Homework) Stefan Coreth PY 208, section 002M, Fall 2010 Instructor: Laura I. Clarke Web Assign The due date for this assignment is past. Your work can be viewed below, but no changes can be made. This is an impossible pattern of electric field. The angle between E 1 and is 90 degrees. Only the curved surface of the cylinder gives a nonzero contribution to the net electric flux.
