NAME: _____________________________________________________

1. Explain the Law of Electric Charges (pg. 462) ________________________________________ ________________________________________________________________________________

2. What happens when a charged object is brought near a neutral object? (Explain what happens to the electrons within the object). ________________________________________________________________________________

3. What is the Electrostatic Series ________________________________________________________________________________

Answer questions 1-4 based on the electrostatic series:

Charging By Contact

1. An ebonite rod was rubbed with silk. (rod has more attraction for electrons)

a) ADD THE CHARGES THAT WILL EXIST BEFORE FRICTION HAS OCCURRED

Silk Rod

Charge: ___________________ Charge: ___________________

b) ADD THE CHARGES THAT WILL EXIST AFTER FRICTION HAS OCCURRED

FRICTION HAS OCCURRED Silk Rod

Charge: ___________________ Charge: ___________________

c) ADD THE CHARGES THAT WILL EXIST WHEN THE ROD TOUCHES NEUTRAL PAPER (rod has more attraction for electrons than paper)

Paper Rod

Charge: ___________________ Charge: ___________________

2. A glass rod was rubbed with rubber. (rubber balloon has more attraction for electrons)

a) ADD THE CHARGES THAT WILL EXIST BEFORE FRICTION HAS OCCURRED

Rubber Rod

Charge: ___________________ Charge: ___________________

b) ADD THE CHARGES THAT WILL EXIST AFTER FRICTION HAS OCCURRED
