The electric field has been measured to be horizontal and to the right everywhere on the closed box as shown in Figure 22.104. All over the left side of the box E1 = 100 volts/m, and all over the right (slanting) side of the box E2 = 300 volts/m. On the top the average field is E3 = 150 volts/m, on the front and back the average field is E4 = 175 volts/m, and on the bottom the average field is E5 = 220 volts/m. How much charge is inside the box? Explain briefly
