# A student rubs a balloon on their hair. The balloon becomes negatively charged. Explain why two balloons, both charged in this way, repel each other when brought close together.

> Eduqas GCSE Physics — 7.3 Static electricity – forces and electric fields · Explain · 4 marks

## Mark scheme (4 marks)

1. Rubbing transfers electrons from the hair to the balloon
2. Both balloons carry the same type of charge (negative)
3. Like charges repel
4. The repulsive force acts without the balloons touching, through the electric field
