<<< Flux of Electric Field >>> 
(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 xaxis 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 xaxis. 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.
