When a plastic rod is rubbed with a wool cloth, the wool acquires a positive charge. What is the best explanation for this effect?

Question

a
electrons are transferred to the cloth
b
electrons are transferred to the rod
c
protons are transferred to the rod
d
protons are transferred to the cloth

Answer 1

The best explanation for the phenomenon where the wool cloth acquires a positive charge when rubbed against a plastic rod is:

a) electrons are transferred to the cloth

When the plastic rod is rubbed with the wool cloth, electrons (which carry a negative charge) are transferred from the wool to the plastic rod. This leaves the wool with a net positive charge and the plastic rod with a net negative charge.
