(1) An electric field Eo is oriented so that it makes an angle of 60 (clockwise) with the vertical. A disk of diameter D is placed in the region where the Eo is set up. Determine the flux of the electric field through the disk, when between its normal and the x-axis there is an angle of:      (a) 30    (b) 90     (c) 120    (d) 0

 
(2) A wire has been bent to shape a rectangle of sides 'a' and 'b', and then it has been placed in a region where there is an electric field Eo at an angle of  75 with the x-axis. Calculate the flux of the electric field through this rectangle, when its normal makes the following angles with the Eo field. (a) 60 (b) 180 (c) 0 (d) 90

Solution.-

The 75 orientation of the electric field plays no role in the solution of this problem because the angles between the normal to the rectangle and the electric field are data.
