a.) An object carries a charge of -6.1 µC, while
another carries a charge of -2.0 µC. How many electrons
must be transferred from the first to the second object so that
both objects have the same charge?
b.) Suppose a thin conducting wire connects two conducting
spheres. A negatively charged rod is brought near one of the
spheres, the wire between them is cut, and the charged rod is taken
away. Which one of the following is true?...

a) You're holding a small metal ball suspended on a piece of insulating string from the ceiling. You and the ball are both initially electrically neutral. A positively charged rod is brought near to the metal ball; you then let go of the metal ball. You now have a positive electric charge. This process is called charging by 1.) Electroscope. 2.) Insulation. 3.) Conduction. 4.) Induction. b) Charged glass and plastic rods hang by threads. An object attracts the glass...

1. For each statement select P for Positive, N for Negative, or Z for Zero charge (Neutral). (If the first answer is positive, the second negative, and the third neutral (zero net charge), enter PNZ. Do not enter spaces) A) A negatively charged rod is brought close to a neutral isolated conductor, but it does not touch. The conductor is then grounded while the rod is kept close. If the ground connection is first broken, and THEN the rod is...

1) A negatively charged Teflon (plastic) rod is held near two initially neutral aluminum pie plates that are touching as shown at right. The plates are held using insulating cups. The Teflon rod never touched the pie plates, and no sparks have jumped. Negatively charged Teflon rod a. Is the magnitude of the net charge of the small pie plate greater than, less than, or equal to the magnitude of the net charge of the large pie plate? If the...

electric charges 1. When a rod of the same charge is rought close to the knob of a charged metal leaf electroscope, what is the effect on the metal leaves? Draw a sketch that explains that effect. 2. When a rod of the opposite charge is brought close to the knob of a charged metal-leaf electroscope, what effect does this have on the metal leaves? Again, draw an explanatory sketch. 3. what is the procedure for giving an electroscope a...

7. Sphere A carries a net charge and sphere B is neutral. They are placed near each other on an insulated table. Which statement best describes the electrostatic force between them? a. There is no force between them since one is neutral. c. There is a force of attraction between them. b. There is a force of repulsion between them. d. The force is attractive if A is charged positively and repulsive if A is charged negatively. Use the diagram...

Will a penny be slightly more massive if it has a negative or a positive net charge? (Think very small!!) (a) It will be just as massive either way. (b) More massive if negative. (c) More massive if positive. A charged conducting object is brought close to a neutral insulating object. Which of the following is true? (a) The objects will repel. (b) The objects will attract. (c) Nothing will happen, no attraction, no repulsion. (d) The objects will repel...
