6. Guided Practice A The rod is moved close to the conducting sphere but never touches B The rod touches the conducting sphere on the right C The two neutral conducting sphere’s touch. A negatively charged conducting rod is brought close, then sphere A and B are separated and the rod is taken away. AA BB For each of the following, draw the charge distribution and specify whether conduction, induction, and/or polarization is occurring. D. Draw a neutral insulating sphere with 5 positive and 5 negative charges.

7. E#1 Electric Charge & Conducting Sphere’s Practice 1 (66.) Two initially uncharged conductors, 1 and 2, are mounted on insulating stands and are in contact, as shown above. A negatively charged rod is brought near but does not touch them. With the rod held in place, conductor 2 is moved to the right by pushing its stand, so that the conductors are separated. Which of the following is now true of conductor 2? (A) It is uncharged. (B) It is positively charged. (C) It is negatively charged. (D) It is charged, but its sign cannot be predicted. 2(110.) A charged rod is placed between two insulated conducting spheres as shown. The spheres have no net charge. Region II has the same polarity as Region (A) I only (B) III only (C) IV only (D) I & III only (E) I & IV only a. A neutral rod is places on a positively charged conducting sphere. What will be the charge of the conducting sphere? Draw the resulting configuration. c. How much charge do 10 electrons have? d. How much charge do 25 protons have? b. Three neutral conducting spheres touch. Draw the charge distributions after a positively charged rod is placed near the left sphere and a negatively charged rod is placed near the right sphere.
