5.5 Exercise 13

Two thin parallel conducting plates are placed 2.0 cm apart. Each plate is 2.0 cm on a side; one plate carries a net charge of $8.0 \mu \text{C} ,$ and the other plate carries a net charge of $−8.0 \mu \text{C} .$ What is the charge density on the inside surface of each plate? What is the electric field between the plates?
