Electrical forces between charges are strongest when the charges are 

• far apart. 
• close together. 
• The electrical force is constant everywhere.

A positive charge and a negative charge held near each other are released. As they move, the force on each particle 

• increases. 
• stays the same. 
• decreases.

Particle A has twice as much charge as particle B. Compared to the force on particle A, the force on particle B is 

• half as much. 
• two times as much.
•  four times as much. 
• the same. 

Electric field is a...

• scalar.

• vector.
