- Q1: What force is generated when a plastic comb is rubbed on dry hair?
Answer: Electrostatic
Explanation: Rubbing a comb builds electric charges, which exert an electrostatic force. - Q2: What kind of force is electrostatic—contact or non-contact?
Answer: Non-contact
Explanation: Electrostatic force does not need physical contact and acts from a distance. - Q3: What type of charge do objects develop after being rubbed?
Answer: Static
Explanation: Rubbing certain materials produces static electricity, which causes electrostatic forces. - Q4: What kind of objects can be attracted by a charged balloon?
Answer: Light
Explanation: Light objects like paper bits are attracted due to the electrostatic force created by a charged balloon. - Q5: What kind of force is involved when small pieces of paper jump toward a rubbed scale?
Answer: Electrostatic
Explanation: The rubbed scale gets charged and exerts electrostatic attraction on the paper. - Q6: What is the nature of force between unlike charges?
Answer: Attractive
Explanation: Opposite electric charges attract each other due to electrostatic force. - Q7: What is the nature of force between like charges?
Answer: Repulsive
Explanation: Similar electric charges repel one another when electrostatic force acts. - Q8: What material, when rubbed, can develop a static charge and attract dust?
Answer: Plastic
Explanation: Rubbing plastic develops static electricity that can attract dust particles. - Q9: What do we call the force that acts on objects without contact due to electric charges?
Answer: Electrostatic
Explanation: Electrostatic force acts due to the electric charge and does not require contact. - Q10: What is the effect called when objects stick or move due to static electricity?
Answer: Attraction
Explanation: Electrostatic forces can cause attraction between charged and neutral objects.
