50% Part (a) What is the charge per unit length, in coulombs per meter, on the copper rod?
50% Part (b) Suppose the rod passes through a Gaussian surface which is a cube with an edge length L =6.5 cm as, shown. The rod is perpendicular to the faces through which it passes, and it extends well beyond the edges of the sketch. What is the electric flux, in newton squared meters per coulomb, through the cube?
