Show answer Hide answer
Answer
They move apart — they repel each other.

Explanation

  • Rubbing both balloons with the same cloth gives them the same kind of charge.
  • Like charges repel each other.
  • So the two balloons push apart.
Same charges repel, so the balloons move away from each other.
