A glass rod and a piece of silk cloth are initially uncharged. The glass rod is rubbed with the silk cloth, and both become charged. The glass rod becomes positively charged because some charged particles move in the charging process.
What is the charge acquired by the silk cloth, and which particles moved during this process?
Negative charge on silk cloth, electrons moved
Negative charge on silk cloth, protons moved
Positive charge on silk cloth, electrons moved
Positive charge on silk cloth, protons moved
