CHAPTER 1: ELECTROSTATICS

When an object gains electrons it becomes __________

• Neutral

• Positively charged

• Negatively charged

• A dinasour

Two like charges

• neutralize each other.

• repel each other.

• must be neutrons.

• attract each other.

What is the SI unit used to measure force? 

• pounds 
• grams 
• newtons 
• friction

The law of conservation of charge states that...

• all atoms have more protons than electrons
• only protons can be rubbed off of an atom
• charge cannot be created or destroyed
• charge cannot be transferred 

Define electric field strength

• Force per unit charge

• Force per unit positive charge acting on a stationary point charge

• Rate of acceleration of a charge in an electric field

• Electric force per unit charge acting on a stationary point charge in an electric field

A volt is a unit of

• charge

• electric potential

• energy

• work

• current

What is the SI unit for charge?

• Joules

• Coulombs

• Newtons

• Meters
