1. A surface charge can be produced on insulators by
a. grounding
b. induction
c. polarization
d. contact

2. Unlike insulators, conductors can be charged by
a. grouding
b. induction
c. polarization
d. contact

The easy way to charge an insulator is by contact. Insulators cannot be charged by induction, but conductors can.
