When a balloon is rubbed on clothes it acquires a charge by ___________.

• Induction

• reduction

• conduction

• convection

TRUE or FALSE: According to Coulomb's Law, the greater the separation of distance between two charges the greater the magnitude of the electrostatic force.

• True

• False

TRUE or FALSE: The mass of a single electron is equal to 9.109x10^-31 C.

• True

• False

What happens to the field strength as the distance between two charged objects decreases?

• the strength stays the same

• the strength increases

• the strength decreases

• the strength fluctuates between positive and negative

What does the Law of Conservation of Charge state?

• like charges repel and opposites attract

• positive charge fields point away from a charge; negative points toward

• charges cannot be created nor destroyed, only transferred

Where can an electric field be found?
