If a negatively charged rod touches a conductor, the conductor will be charged by what method? 

• Friction

• Conduction

• Induction

• Convection

Which of these is the best definition of polarization?

• The object gains a positive or negative charge from another object.

• The charges in a neutral object separate due to a nearby charged object.

• Charges on a neutral object jump off onto a charged object due to attraction of opposite charges.

• Two objects attract each other because they are both charged.

Two storm clouds rub against each other giving one cloud a positive charge and one a negative charge.  This is an example of charging by

• Conduction

• Convection

• Friction

• Induction

A charged balloon is brought near an electroscope but DOES NOT touch the electroscope.  This is an example of charging by

• Conduction

• Convection

• Friction

• Induction
