this is just a physics practice problem I already did it I just wanted to compare answers. its is in electrostatic charged.

Electrostatic Assignment #1 1. Compare the electron, proton and neutron with respect to mass and charge. Charge Mass Particle Symbol Electron Protor 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. What is the law of electrostatic charges? 6. Who gave the present name to the 2 types of charges? 7. Why is a normal atom neutral? 8.
