Electrostatic Forces and Charges

The video tutorial demonstrates an activity to understand electrostatic force. It involves inflating a balloon, rubbing it with paper, and observing the attraction between the balloon and small paper pieces. This activity illustrates how a charged balloon can exert an electrostatic force on nearby objects, even without direct contact. The tutorial concludes by explaining that electrostatic force is a type of force that acts at a distance.

What is the first step in the activity to understand electrostatic force?

• Rub the balloon with another paper

• Tie the balloon with a thread

• Inflate the balloon

• Cut the paper into small pieces

What should you do after inflating the balloon?

• Cut the paper into small pieces

• Place the paper pieces on the table

• Tie the open end of the balloon with a thread

• Rub the balloon with another paper

What happens when the balloon is brought near the small pieces of paper?

• The paper pieces change color

• The paper pieces move away from the balloon

• The paper pieces remain stationary

• The paper pieces are attracted to the balloon

What charge does the balloon acquire when rubbed with paper?

• Positive charge

• Negative charge

• Both positive and negative charges

• No charge

What is the term used to describe a body that has acquired an electrostatic charge?

• Conductive body

• Charged body

• Magnetic body

• Neutral body

What type of force is exerted by a charged body on another body?

• Electrostatic force

• Nuclear force

• Gravitational force

• Magnetic force

Which of the following is an example of a force that acts at a distance?

• Tension force

• Normal force

• Frictional force

• Electrostatic force
