Problem 19.78 14 of 14 > When a charged balloon sticks to a wal the downward...
When a charged balloon sticks to a wall, the downward gravitational force is balanced by an upward static friction force. The normal force is provided by the electrical attraction between the charged balloon and the equal but oppositely charged polarization induced in the wall's molecules. If the mass of a balloon is 2.1 g, its coefficient of static friction with the wall is 0.70, and the average distance between the opposite charges is 0.80 mm, what minimum amount of charge...

The reason a charged balloon will stick to a wall is that A) the charge is slightly sticky and acts like glue. B) the rubber of the balloon simply sticks to walls. C) none of the other answers. D) induced opposite charges in the wall are closer than other wall charges. E) electrons transfer back and forth between the wall and the balloon. Two charges are separated by a distance d. If both the charges are doubled, what happens to...
2. David rubs his hair on a balloon which becomes charged. The balloon then sticks to a wall. The balloon remains stuck on the wall. Note that the magnitude of the electric force, Felectric, is given by Felectric = μsFN , where μs is the coefficient of static friction. If μs= 0.5, the mass of the balloon is 20g, and the radius of the balloon (assume spherical) is 20 cm. Determine the following: Does the balloon become negatively or positively...
