What electrical charges do two balloons have if they repel each other

A negative and neutral

B Both are neutral in charge

C positive and negative

D positive and positive

C positive and negative

When two balloons repel each other, it indicates that they have the same type of charge. Now, let's review the options given:

A) A negative and neutral: This option suggests that one balloon is negatively charged and the other balloon is neutral. Since opposite charges attract each other, this option doesn't align with the fact that the balloons repel each other. So, A can be eliminated.

B) Both are neutral in charge: This option suggests that both balloons have no charge. If they have no charge, they would not repel each other. Hence, B can be eliminated.

C) Positive and negative: This option suggests that one balloon is positively charged while the other is negatively charged. Since opposite charges attract, this option is consistent with the observation that the two balloons repel each other. Therefore, C is the correct option.

D) Positive and positive: This option implies that both balloons are positively charged. Like charges repel each other, so this option is inconsistent with the fact that the balloons repel. Therefore, D can be eliminated.

Hence, the answer is C) positive and negative charged balloons.
