Apologies for the incorrect previous response. If two balloons repel each other, it means that they have the same electrical charge. Therefore, the correct answer is positive and positive.
The correct answer is "positive and negative".
When two balloons repel each other, it indicates that they have the same kind of charge. According to the law of electric charges, like charges repel each other, whereas opposite charges attract each other.
To understand the charges on the balloons, you can perform a simple experiment using a comb and a piece of wool fabric. Firstly, rub the comb against the wool fabric. This action transfers electrons from the wool fabric to the comb, leaving the comb negatively charged and the wool fabric positively charged.
Now, bring the negatively charged comb close to the balloons. Since the balloons are initially neutral in charge, the negatively charged comb will attract and take away some of the electrons from the balloons. As a result, the balloons become positively charged. The positively charged balloons then repel each other, indicating that both balloons have the same kind of charge, which is positive.
Therefore, the correct answer is "positive and negative".
