    Celebration of Knowledge 2/21/2020 ber balloon gains excess electrons when a strange physics professor rubs the balloon in is hair. If the professor then touches the balloon to a wall, and it sticks, the balloon will be inducing a charge on the wall that is equal and opposite to its charge. This was demonstrated in class! (a) (5 points) Draw and label the balloon while it is stuck to the wall. Be sure to indicate the charges that are on...
