If you rub a glass rod with a piece of silk, the rod becomes positively charged. This means that

• Friction destroyed electrons in the rod.

• The silk has accepted electrons from the glass and is now negatively charged

• Protons have moved to the rod.

• The glass rod has accepted positive charges from the silk and is now positively charged

What charge does a proton have?

• negative (-)

• positive (+)

• neutral

• no charge
