Electrostatics: Potential

If 1.0 joule of work is required to move 1.0 coulomb of charge between two points in an electric field, the potential difference between two points is

The diagram represents a positively charged particle about to enter the electric field between two oppositely charged parallel plates.

The electric field wil deflect the particle

• Into the screen

• Out of the screen

• Toward the top of the screen

• Toward the bottom of the screen

What is the total amount of work required to move a proton through a potential difference of 100 Volts?

• They both experience the same force

• They both experience zero force

Which electrical unit is equivalent to one joule?

• Volt per meter

• Ampere-volt

• Volt per coulomb

• Coulomb-volt

If 60 joules of work is required to move 5.0 coulombs of charge between two points in an electric field, what is the potential difference between these points?

• 5.0 V

• 12 V

• 60 V

• 300 V

• Neutron, because it has the greatest mass

• Neutron, because it is neutral

• Electron, because it has the smallest mass

• Proton, because it is farthest from the negative plate

Answer explanation

In a uniform electric field, all points in the field will have the same strength.
