Electrostatics Basics

The unit used to measure electric charge is...

• newton

• Coulomb

• meter

• volt

Which of the following is the most likely way for an object to become electrostatically charged? 

• to lose protons

• to gain electrons

• to gain neutrons

• to gain protons

If an object has an electrostatic charge, it has...

• an imbalance of neutrons and protons

• the same number of protons and electrons

• an imbalance of protons and electrons

• the imbalance of electrons and neutrons

 Why is electrostatic charge caused by the gain or loss of electrons?

• because electrons are bound in the nucleus

• because neutrons are bound in the nucleus

• because protons cannot leave their orbital shells around the nucleus

• because protons are bound in the nucleus ,and electrons are not
