EXERCISE 1: WHEREIN THE GREAT SANTINI TRIES TO DESIGN A MAGIC TRICK After reading a news article about NASA scientists building an "electrostatic #1 negatively charged plastic levitator," the Great Santini decides to support (fixed) revive his failing magic act by levitating charged objects. His planned trick is shown in the figure below: a charged spherical glass ball of mass 1 kg (labelled #2) is to be 20 cm suspended directly underneath a negatively charged plastic support (labelled #1). He plans to charge the support and the ball by using friction (e.g. by rubbing the objects with silk or fur as #2 appropriate). He asks his niece (who 1 kg (for now) happens to be one of the top students in Physics 212 at Penn State) if the trick might work. She thinks
