2. A rubber balloon gains excess electrons when a strange physics professor rubs the balloon in his hair. If your strange physics professor decided to do this, answer the following questions about the charged balloon. (a) (6 points) If the professor holds the balloon 12 mm in front of a wall (assume that the wall has neutral charge), will the charges on the wall be affected by the balloon. Briefly explain if and how the wall will respond to the charged balloon. Be sure to use language from class and diagrams when necessary. g
