Question

please sir, write clearly by hand

Q1) A uniform electric field of magnitude 8x 102 N/C passes through a circle of radius 13 cm. What is the electric flux through the circle when its face is (a) perpendicular to the Geld lines, (b) at 30° to the field lines, and (c) parallel to the field lines?
