Question 51

An acetate rod and a dry cloth are initially uncharged.

The rod is rubbed with the cloth and they both become charged. Inside the atoms of the materials, only electrons can be transferred by friction. The rod becomes positively charged because some charged particles move from the rod to the cloth.

What is the charge on the cloth and which particles moved in the charging process?

A

Charge on cloth: positive; Particles that moved: protons

B

Charge on cloth: positive; Particles that moved: electrons

C

Charge on cloth: negative; Particles that moved: protons

D

Charge on cloth: negative; Particles that moved: electrons
