Step 1: Determine the charge on the glass rod (A). When a glass rod is rubbed with wool, the glass rod tends to lose electrons and becomes positively charged. Step 2: Determine the charge on the plastic rod (B). When a plastic rod is rubbed with cat's fur, the plastic rod tends to gain electrons and becomes negatively charged. Step 3: Analyze the interaction between the rods. The problem states that the two rods attract each other. Opposite charges attract. Since rod A is positively charged and rod B is negatively charged, they will attract each other, which is consistent with the observation. Step 4: Evaluate the given options. (1) A acquired positive charge & B acquired negative charge. This matches our analysis. (2) B acquired positive charge & A acquired negative charge. This would also result in attraction, but it contradicts the standard charging behavior of glass and plastic with the given materials. (3) Both acquired positive charge. Like charges repel, so this is incorrect. (4) Both acquired negative charge. Like charges repel, so this is incorrect. The correct conclusion is that A acquired a positive charge and B acquired a negative charge. The final answer is (1) A acquired positive charge & B acquired negative charge Send me the next one 📸
