Question 3 of 10intermediate🔧 ApplyShort Answer3 marks

Two balloons rubbed with a woollen cloth are brought near each other. What would happen and why?

Correct Answer

When two balloons are rubbed with a woollen cloth, both balloons acquire similar types of static charges.

Since like charges repel each other, the balloons move away from each other when brought close.

This repulsion occurs due to the electrostatic force acting between the similarly charged balloons.
