Question

What electrical charges do two balloons have if they repel each other
Both are neutral in charge

positive and negative

positive and positive


negative and neutral

Answer 1

The correct answer is positive and negative. When two balloons repel each other, it means that they have opposite charges. Since both balloons are initially neutral, one of them must have gained a positive charge and the other must have gained a negative charge due to some external influence like friction or contact with another charged object.
