2. We have two infinite plane sheets of charge, with charge density o = 6 uC/m and o = -6 uC/m2. a) If the two planes are parallel, 0.10 m apart, find the electric field in each of the three regions (above both planes, between the planes, and below both planes). b) If the two planes intersect at right angles, find the electric field in each of the four regions. c) Repeat part a if the charge densities of the two planes are o = 6 uC/m and o = -4 uc/m2. d) Repeat part b if the charge densities of the two planes are o = 6 uC/m and o = -4 uC/m2
