When a Piece of Paper Is Held with One Face $\degree$

When a piece of paper is held with one face perpendicular to a uniform electric field the flux through it is 25 N . m²/C. When the paper is turned 25 $\degree$ with respect to the field the flux through it is:

A) 0
B) 12 N .m²/C
C) 21 N . m²/C
D) 23 N .m²/C
E) 25 N. m²/C
