5 Questions
What is the effect observed when a charged balloon is brought near pieces of paper?
The pieces of paper are pulled towards the balloon.
What happens to the pieces of paper when they are brought near a charged body?
They acquire an opposite charge and cling to the body.
What force is exerted by a charged body on another charged body?
Electrostatic force
What happens when a charged balloon is rubbed with a paper?
The balloon acquires an electrostatic charge on its surface.
In the context discussed, what does 'charged body' refer to?
A body with an electrostatic charge
Study Notes
Electrostatic Charge and Force
- When a balloon is inflated, tied, and then rubbed with a paper, it acquires an electrostatic charge on its surface, making it a charged body.
- When the charged balloon is brought near small pieces of paper on the floor, the pieces of paper are attracted to the balloon and rise to cling to it.
- This attraction occurs because the pieces of paper acquire an opposite charge when brought near the charged balloon.
- The force exerted by a charged body (the balloon) on another charged body (the pieces of paper) is known as electrostatic force.
- Electrostatic force is an example of a force that can act at a distance, even when the bodies are not in contact.
- The same phenomenon can be observed when using pepper and salt in place of pieces of paper, demonstrating the electrostatic force at work.
This quiz explores the concept of static electricity through a simple experiment involving a charged balloon and pieces of paper. Participants will answer questions about the behavior of the paper bits when brought near the balloon, and the underlying principles of attraction at play. The quiz also prompts users to try the same experiment with pepper and salt for further observation.
