A 4.0 cm² in the x-y plane sits in a uniform electric field E = (2.0 i + 3.0 j +50 k) N/C. Find the electric flux through the square.

Two long, straight, parallel wires of length 4.0m carry parallel currents of 3.5A and 1.2A. (a) if the wires are separated by a distance of 3.5 cm, what is the magnitude of the force between the two wires? (b) Is this force attractive or repulsive? (c) If the currents are in opposite direction (antiparallel), how do the answer to parts (a) and (b) change?
