Charging by Rubbing

  1. Q1: What type of electricity is generated by rubbing two objects together?
    Answer: Static
    Explanation: Rubbing objects creates static electricity due to the transfer of charges.
  2. Q2: What tiny particles are transferred during rubbing to create charge?
    Answer: Electrons
    Explanation: Electrons move from one object to another when they are rubbed, creating charges.
  3. Q3: What charge is developed on an object that gains electrons?
    Answer: Negative
    Explanation: An object gains a negative charge when it receives extra electrons.
  4. Q4: What charge is developed on an object that loses electrons?
    Answer: Positive
    Explanation: Losing electrons makes an object positively charged.
  5. Q5: What is the process of developing electric charge by rubbing called?
    Answer: Friction
    Explanation: Friction between two objects leads to the transfer of electrons, causing charge.
  6. Q6: What type of material, when rubbed, can get charged easily—conductor or insulator?
    Answer: Insulator
    Explanation: Insulating materials like plastic or rubber can easily hold static charge when rubbed.
  7. Q7: What property is shown by unlike charges when brought near each other?
    Answer: Attraction
    Explanation: Unlike charges (positive and negative) attract each other.
  8. Q8: What property is shown by like charges when brought near each other?
    Answer: Repulsion
    Explanation: Like charges (both positive or both negative) repel each other.
  9. Q9: What do we call an object that has an equal number of positive and negative charges?
    Answer: Neutral
    Explanation: An object is neutral when its positive and negative charges are balanced.
  10. Q10: What simple activity demonstrates charging by rubbing using a plastic scale?
    Answer: Combing
    Explanation: When a plastic comb is rubbed on dry hair, it becomes charged and can attract small paper bits.
