PHYC 101 FINAL

a neutral object

has equal numbers of protons and electrons

An insulator differs from a conductor in that an insulator

has fewer freely moving electrons

The electroscope detects

static electricity

Charge carriers in a metal are electrons rather than protons because electrons are

all of these; negative, smaller, loosely bound

An electric charge that results from the presence of a charged object nearby (no direct contact) is called

an induced charge

Static electric charges are charges that

are stationary charges

a negatively charged rod is brought near a metal conductor. the protons in the metal conductor experience a force of

attraction

Upon entering the room, you observe two balloons suspended from the ceiling. You notice that instead of hanging straight down vertically, the balloons seems to be repelling each other. You can conclusively say ...

both balloons are charged with the same type of energy

A charge resulting from contact between objects is called

conduction

Which atomic particle caries a negative charge

electron

a positively charged rod is brought near a metal conductor. which, if any, particles move toward the rod?

electrons

What happens when a positively charged rod is brought near a neutral plastic ball?

electrons in the ball are attracted to the near side of the ball

a negatively charged rod is brought near a metal conductor. the electrons in the metal conductor experience a force of

no force at all
