A long coaxial cable carries a volume charge density described by p = ks4 (where k is a constant) on the inner insulating cylinder (radius a), and a uniform surface charge density ? (sigma) on the outer conducting cylindrical shell (radius b). Assume that the coaxial cable is electrically neutral (i.e. Qtotal = 0) and you may ignore the edge effects of the cylindrical shells.a. Determine the electric field everywhere in terms of the total charge per unit length of the inner cylinder ?inner (lambdainner).

A rectangular box (L = 30 cm, w = 28 cm, h = 11 cm) has a net charge gencl enclosed inside it. The figure below shows three electric fields, each pointing to the left, measured on the surface of the box. E₁ is uniform over the right side of the box, E2 is uniform over the top, bottom, front, and back sides, and E3 is uniform over the left side. If the magnitudes of the electric fields are E₁ = 550 N/C, E₂ = 900 N/C, and E3 = 1300 N/C, determine the value of gencl. Note that the figure is not to scale. με Ē₁ L E W h
