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 charged when david rubs his hair to it?
- Draw a free body diagram of the balloon and show the wall for reference
- Determine the amount of charge required to keep the balloon stuck to the wall.

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!

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...
