A glass rod and a dry cloth are initially uncharged. The glass rod is rubbed with the cloth and becomes positively charged because some charged particles are transferred.
What is the resulting charge on the cloth and which particles are transferred in this process?
Cloth becomes negatively charged; electrons are transferred.
Cloth becomes negatively charged; protons are transferred.
Cloth becomes positively charged; electrons are transferred.
Cloth becomes positively charged; protons are transferred.
