PHY Electric Potential

An electron volt is

• the force acting on an electron in a field of 1 N/C 
• the force required to move an electron 1 meter 
• the energy gained by an electron in moving through a potential difference of 1 volt 
• the energy needed to move an electron through 1 meter in any electric field 

What is the shape of the electric field between two flat charged plates.

• A uniform field between the plates with a curved field at the ends.

• A uniform field between the plates.

• A spherical field increasing towards infinity.

• A spherical field decreasing towards infinity.
