In one part of the room, there are two balloons - one hanging straight down and the other being attracted to it. This is evidence that _____.

• balloon A is charged and balloon B is neutral

• balloon B is charged and balloon A is neutral

• balloon A is neutral and balloon B is negative

• balloon A is neutral and balloon B is positive

• ... nonsense! This would never happen if the balloons are identical and simply suspended by strings. They will attract each other and both be deflected from a vertical orientation.
