8.A negatively charged rod is brought near a neutral piece of aluminum foil suspended on a thread.a. Explain what happens before they contact.b. Explain what happens after they contact.9.a.Compare the distribution of charge on two rods, an aluminum and an ebonite rod, if each rodhas been charged by contact at one end while supported by a good insulator.b.How would you use an electroscope to verify your answer?10. If a negatively charged rod is brought near the top of a positively charged electroscope, whathappens to the leaves and why?The rest is in the image

1. Compare the electron, proton and neutron with respect to mass and charge. Mass Particle Symbol Charge Electron Proton Neutron Alpha Beta 2. If a rubber rod is rubbed with fur, the rod becomes negatively charged. What is the source of the charge? 3. If a glass rod is rubbed with silk, the rod becomes positively charged. What is the source of this charge? 4. If you hung a charged rubber rod so that it is free to swing, and brought a similarly charged rubber rod near it, what would you expect to happen? 5.
