A group of students investigated the properties of an electrophorus similar to the one shown here, The conducting plate is shown with an induced separation of charge. light bulb fee aluminum plate +++++++++++ ++ + ++ conducting plate Charged Styrofoam Plate insulated base 1. If the light bulb wire is grounded then electrons will flow from ground to the conducting plate O electrons will flow from the conducting plate to ground positive charge will flow from ground into the conducting plate O electrons will remain stationary in the conducting plate. 2. What must have been the charge on the insulated base? positive no charge O neutral O negative4. Which of the following correctly depict the electric field for a negative charge and a graph of the absolute value of the electric field as a function of distance, for a negative charge? O
