Question 103

A glass rod and a piece of silk cloth are initially uncharged. The glass rod is then rubbed with the silk cloth, causing both to become charged. The glass rod becomes positively charged because some charged particles move from the glass rod to the silk cloth.

What is the charge on the silk cloth and which particles moved during this charging process?

A

Charge on silk: positive; Particles that moved: protons

B

Charge on silk: negative; Particles that moved: electrons

C

Charge on silk: positive; Particles that moved: electrons

D

Charge on silk: negative; Particles that moved: protons
