1. | A glass rod is charged to +8-0 nC by rubbing. a. Have electrons been removed from the rod or protons added? b. How many electrons have been removed or protons added? 3. | A plastic rod that has been charged to 15 nC touches a metal sphere. Afterward. the rod's charge is -10 NC. a. What kind of charged particle was transferred between the rod and the sphere, and in which direction? That is, did it move from the rod to the sphere or from the sphere to the rod? 13. How many charged particles were transferred? 5. II What is the total charge of all the electrons in 1.0 L of liquid water?11. II You have two neutral metal spheres on wood stands. Devise a procedure for charging the spheres so that they will have like27. I| The electric field at a point in space is E = (4007 + 100 j ) N/C. a.
