Sphere X has a charge of +10 C and sphere Y is neutral. Which statement is correct? After some time, Y is still neutral. After some time, Y has a net positive charge. After some time, the charges on X are transferred to Y. X and Y each have a net charge of +5 C. 2 / 5 2) Spheres X and Y have equal positive charges. A light negatively charged object N is placed in the position shown. In which direction does N move? C A B D 3 / 5 3) Which of the following can attract a stream of water? Assume the stream of water has neutral charge. (1) A negatively charged insulator. (2) A negatively charged conductor. (3) A neutral conductor. (1) and (2) only (1) and (3) only (1), (2), and (3) (2) and (3) only 4 / 5 4) A positively-charged oil drop is suspended at rest at position P between two charged plates as shown. What will happen to the same positively-charged oil drop if it is at position Q? The oil drop will accelerate towards the negative plate. The oil drop will move at constant speed towards the negative plate. The oil drop will move at constant speed towards the positive plate. The oil drop will remain at rest. 5 / 5 5) Two uncharged metal spheres X and Y are placed on insulating stands and are brought into contact with each other. Another identical uncharged metal sphere Z is placed near to them. What are the net charges on X, Y and Z when a positively charged rod is brought near X? X: negative, Y: positive, Z: neutral X: negative, Y: positive, Z: negative X: negative, Y: negative, Z: negative X: positive, Y: negative, Z: neutral Your score is Restart quiz
