Electric Charges and Fields

One of the fundamental properties is the electromagnetic property. Charge cannot be destroyed by any process and this contributes formally to the law of charge conservation.

Question

Q2) A disk of radius 0.1 m is oriented with its normal unit vector n at 30° to a uniform electric field of
magnitude 2 x 103 N/C. (Since this isn't a closed surface, it has no "inside" or "outside." That's why
we have to specify the direction of n in the figure.)
(a) What is the electric flux through the disk?
(b) What is the flux through the disk if it is turned so that n is perpendicular to E?
(c) What is the flux through the disk if n is parallel to E?
