This is due for C block next Thursday. For E block, next Friday (do the previous one for wednesday).
1. What is Coulomb's law? Give a description and a mathematical expression - don't forget to identify what the variables represent.
2. If the charge of one proton is 1.6 x 10^-19 C, how many protons are required to make a coulomb of charge?
3. What is the charge of a balanced hydrogen atom? Does this answer change for deuterium (an extra neutron in the nucleus)?
4. What is the charge of a helium atom that is missing an electron?
5. What is the force that exists between two 5 coulomb charges that are 0.05 m apart?
6. Coulomb's law is an "inverse square" law. What does that mean? What happens to the force between charged ifmthe distance between them is doubled? Tripled? Halved?
