Questions and Answers

What is the result of bringing a negatively charged object close to a neutral metal object?

  • The electrons are attracted to the negatively charged object.
  • No charges are transferred between the objects.
  • The electrons are repelled on the other side away from the negatively charged object. (correct)
  • The neutral metal object becomes positively charged.

    • What is the method of charging that occurs when two objects are in physical contact with each other?

  • Charging by induction
  • Charging by friction
  • Electrostatic charging
  • Charging by conduction (correct)

    • What is the purpose of the negatively charged rod in Figure 1.1.7?

  • To attract positive charges in the metal sphere
  • To induce positive charges in the side of the sphere near the rod (correct)
  • To repel negative charges in the metal sphere
  • To transfer negative charges to the metal sphere
