8. Pull the required charges to obtain the arrangements shown below (one at the time). Use the superposition principle and: a. Draw the net electric field at the position of the E-field sensor. b. Write an expression for the net electric field at the position of the E-field sensor (show all your work). c. Find the magnitude and direction of the net electric field at the position of the E-field sensor (click on "show numbers" and verify your answers Note all charges are fixed at the grid, and 1 box = 0.1 m.
