You take the balloon and stick it to the ceiling. Why does it stick to the ceiling? a.Because the ceiling is charged with the same charge as the balloon. b.Because the ceiling is charged with the opposite charge to the balloon. c.Because the ceiling is electrically neutral, but charges in the ceiling become polarized when the charged balloon is nearby, allowing it to attract the balloon. d.Because there must be some chewing gum on the ceiling. ***4.How does the force between ceiling and balloon change as the balloon approaches the ceiling? a.Increases as balloon gets closer b.Independent of separation distance c.Decreases as balloon gets closer d.No force until the balloon and ceiling are in contact ****5. You hold the balloon near a second balloon that you also rubbed on your hair. The 2 balloons will a.Attract each other b.Repel each other c.No force between them d.Can't tell without more information ****6.. If the balloon has a mass of 5g, what is the minimum electrostatic force needed to keep it stuck to the ceiling? a.0.005 N b.0.05 N c.0.5 N d.5 N e. Can't tell without more information ****7. Approximately what number of charges will be required to produce that amount of force? Make regular assumptions... e.g. for instance you can assume the charges are 0.5mm (5 x 10-4 m) apart.Explanation / Answer
