Electrostatics - Conduction

What do we mean when we say an object is positively charged?

• it has more electrons than protons

• it has more protons than electrons

• it has equal amounts of protons and electrons

• it has no electrons

When an object is charged by friction, the following happens

• protons are transferred from one object to the other

• electrons are transferred from one object to the other

• both protons and electrons are transferred from one object to the other

• more protons are transferred from one object to the other
