When a glass rod is rubbed with silk, then which type of charge is created on it?

  1. A
    Positive charge
  2. B
    Negative charge
  3. C
    Electric charge
  4. D
    None of the above

Solution & Step-by-step Explanation

When a glass rod is rubbed with a silk cloth, electrons are transferred from the glass to the silk due to friction. Because the glass rod loses electrons, it acquires a net positive charge, while the silk becomes negatively charged.
