Part A. Multiple Choice Select the letter that corresponds to your answer. Write your answer in UPPERCASE! 1. Two parallel plates have equal but opposite charges. The electric force on a negative charge placed near the center of the plates is a. perpendicular to the plates and points toward the positive one. b. perpendicular to the plates and points toward the negative one. c. parallel to the plates. d. zero. 2. What will happen to the magnitude of the electric field If you Increase the magnitude of the charge twice? a. Increase twice b. Increase 4x c. Decrease by 1/2 d. Decrease by / 3. Given the figure on the right, which of the following statement is correct in order to get the electric flux? a. Normal line is perpendicular to the Electric field; therefore, the angle to use is 90'. b. Electric field is perpendicular to the surface; therefore the angle to use is 90" c. Electric Field is parallel to the normal line; therefore, the angle to use is 0 d. Electric field line is parallel to the surface; therefore, the angle to use is 0oGiven the side to get the electric flux3astatement is correct in order to get th a. Normal line is perpendicular to the Electric field; therefore, the angle to use b. Normal line is perpendicular to the surface: therefore the angle to use Is c. Electric Field is parallel to the normal line; therefore, the angle to use Is 90 d. Electric field line is parallel to the surface; therefore, the angle to use is 90 5. If the electric field is parallel to the surface area, which of the following Is CORRECT? a. Angle between the normal line and the electric field line is 90; therefore, electric flux is zero. b. Angle between the normal line and the electric field line is 0; therefore, electric flux Is zero. c. Angle between the normal line and the electric field line is 90; therefore, electric flux is the product of electric field and the area. d. Angle between the normal line and the electric-field line is 0: therefore, electric flux is the product of electric field and the area. 6. Rub the balloon on your hair; It was observe that the balloon will attract the hair by some mysterious force. Why is that so? a. The hair becomes positively charge and the balloon becomes negatively charge so they will attract each other. b. The balloon becomes positively charge and the hair becomes negatively charge so they will attract each other. c. The balloon becomes neutrally charge and the hair becomes negatively charge so they will attract each other. d. The hair becomes positively charge and the balloon becomes neutrally charge so they will attract each other. 7. Which of the following is the correct symbol for electric field? a. C C. N/C d. E b. d8. Two materials that possess like charge repels and opposite charge attracts because of what? a. Electric Charge c. Electric Field b. Electrostatic Force d. Electric Flux 9. Which of the following statement is not true about electric charge? a. Electric charge is the amount of energy that passes from one body to another. b. Electric charge has 2 basic properties. c. Electric charge behaves as scalar quantity. d. Electric charge can neither be created nor destroyed, but it can be transferred. 10. Two balloons will rub on your hair; the balloons will push each other away because a. One of the balloons will be negatively charged and the other one will be negatively charged, so they will repel each other. b. Both balloons will be positively charged as they transferred electrons to the hair, so they will repel each other. c. Both balloons will be negatively charge as the hair transferred electrons, so they will repel each other. d. None of the above
