1. Explain how an object becomes electrically charged and give an example.
2. Describe the difference between a conductor and an insulator, relating this to the transfer of electric charge.
3. Two objects have charges of +2.0 × 10⁻⁶ C and -3.0 × 10⁻⁶ C and are separated by a distance of 0.5 m. Qualitatively, how would the electric force between them change if the distance was doubled?
