Electrostatic Potential

If you walk into a region of space and suddenly feel a force, the space is said to contain a 

• charged object. 
• force field.
• large charge. 
• black hole. 

An electric field has

•  direction. 
• magnitude. 
• Both A and B

Every proton in the universe is surrounded by its own 

• a. gravitational field. 
• b. electric field. 
• c. both A and B 
• d. none of the above

The direction of electric field lines shows the 

• direction of the force on a test positive charge.  
• size of the field.
• c. strength of the field. 
• d. all of the above

Suppose a hollow metal sphere has a large negative charge on it. The electric field strength inside the sphere is 

• a. large and positive.
•  b. zero. 
• c. weak and negative. 
• d. weak and positive. 

Suppose you touch a negatively charged object to a metal sphere so that electrons move from the charged object onto the sphere. After the charged object is moved far away, electrons on the sphere will be

• distributed in small bunches over the sphere's surface.
• distributed evenly over the sphere's surface.
•  pulled off the sphere along with the charged object. 
• located at the place where the charged object was.

Electrical potential energy is the energy a charged object has because of its 

• momentum. 
• location. 
• mass.  
• motion.

A small, positively charged object near a positively charged sphere is moved closer to the sphere. The electrical potential energy of the small object 

• stays the same. 
• decreases. .
• increases

If two negative charges are held close together and then released, the charges will 

• accelerate toward each other.
•  accelerate away from each other. 
• not move.
• move at a constant speed away from each other

Electric potential is defined as potential. 

• electrical potential energy of a charge multiplied by the quantity of the charge.
•  electrical potential energy of a charge divided by the quantity of the charge. 
• electrical potential energy. 
• gravitational
