YOU DON'T NEED TO SHOW WORK ON MULTIPLE CHOICE. EVERYTHING ELSE IS SHORT ANSWER. 5. A charged conductor is brought near an uncharged insulator. Which one of the following statements is true? A) Both objects will repel each other B) Both objects will attract each other C) Neither object exerts an electrical force on the other. D) The objects will repel each other only if the conductor has a negative charge. E) The objects will attract each other only if the conductor has a positive charge Which one of the following statements is true concerning the spacing of the electric field lines in the vicinity of two point charges of equal magnitude and opposite sign? 6. A) The spacing indicates the direction of the electric field. B) The spacing does not depend on the magnitude of the charges C) The spacing is large when the magnitude of the charges is large D) The spacing indicates the relative magnitude of the electric f E) The spacing is small whe n the magnitude of the charges is small. 7. Four point charges are held fixed at the corners of a square as shown in the Which of the five arrows shown below figure. direction of other charges? most accurately shows the the net force on the charge-Q due to the presence of the three 45° 45° 45°Explanation / Answer
5) (B) Both objects will attract each other.
The charged conductor will induce opposite charge on the insulator and then attraction occurs.
6) (D)
7) (C)
