What is the difference between APEelectric and PEelectric? 2. Explain how electric potential and potential difference are related. What units are used for each one? 15 3. Explain why two metal plates near each other will not become charged unless they are connected to a source of potential difference. 4. In a charging process, 1013 electrons are removed from a metal sphere and placed on a second sphere that is initially uncharged. Then the electrical potential energy associated with the two spheres is found to be -7.2 x 10-2 J. What is the distance between the two spheres? 5. A charge moves 2.0 cm in the direction of uniform electric field having a magnitude of 215 N/C. The electrical potential energy of the charge decreases by 6.9 x 10-19 J as it moves. Find the magnitude of the charge on the moving particle. (Hint: The electrical potential energy depends on the distance moved in the direction of the field.) 6. Four particles with charges of 5.0 uC, 3.0 uC, and -5.0 uC are placed at the corners of a 2.0 m x 2.0 m square. Determine the potential difference between the center of the square and infinity. *3.8 x 104 V 7. A 4.00#F capacitor is connected to a 12.0 V battery. a. What is the charge on each plate of the capacitor? b. If this same capacitor is connected to a 1.50 V battery, how much electrical potential energy is stored
