An electric field of magnitude 2.35 v/m is oriented at an angle of 25.0° with respect to the positive z-direction. determine the magnitude of the electric flux througha rectangular area of 1.65 m2 in the xy-plane. n m2/c

Point charges q1=+2.00μc and q2=−2.00μc are placed at adjacent corners of a square for which the length of each side is 1.50 cm . point a is at the center of the square, and point b is at the empty corner closest to q2. take the electric potential to be zero at a distance far from both charges. part a what is the electric potential at point a due to q1 and q2? express your answer with the appropriate units.
