Technician A is correct because rubbing a balloon on a wool sweater transfers electrons from the sweater to the balloon, giving the balloon a negative charge. When placed near a wall, the negatively charged balloon induces a positive charge on the wall's surface, leading to attraction and sticking. Technician B is incorrect because two balloons rubbed on a wool sweater would both be negatively charged and repel each other, not stick together.
