Ch. 33 Electric Potential

Electric field lines between two oppositely charged parallel metal plates will be .. 

• straight lines, randomly spaced
•  straight lines, evenly spaced
• curved lines grouped together in small bunches. randomly spaced.
•  d. curved lines, evenly spaced. e. curved lines,

The electric field inside an uncharged metal ball is zero. If the ball gains a negative charge, the electric field inside the ball will be  

• greater than zero.
• less than zero. 
• zero.

If you use 20 J of work to push a 2-C charge into an electric field, its voltage with respect to its starting position is 

• 10 V. 
• less than 10 V.
•  more then 10 V.

If you use 17 J of work to push a charge into an electric field and then release the charge, as the charge flies past its starting position, its kinetic energy is 

• more than 17 J.    
• less than 17 J.
•  17 J.

The energy that is stored in a capacitor is in the form of 

• the current between its plates.  
• the space between its plates. 
• the electric field between its plates.
• the battery between its plates.
