Two balloons are charged by friction against a wool cloth. How will the balloons react if placed next to each other?Responsesthey will be attracted to each other because they have the same chargethey will be attracted to each other because they have the same chargethey will repel each other because they both have negative chargethey will repel each other because they both have negative chargethey will be attracted to each other because they have opposite chargesthey will be attracted to each other because they have opposite chargesthey will repel each other because they both have opposite charges
GPT 3.5
they will repel each other because they both have the same charge
not an option
GPT 3.5
Apologies for the oversight. The correct answer is:

- they will be attracted to each other because they have opposite charges
