Understanding Uniform Electric Fields

What is a uniform electric field?

• A field that varies in strength at different points

• A field that exists around a single charged particle

• A field that exists between charged parallel plates

• A field that does not exert any force on charged particles

In which direction do electric field lines flow?

• Randomly in all directions

• In a circular motion

• From positive to negative plate

• From negative to positive plate

How is the strength of a uniform electric field indicated?

• By the number of field lines

• By the length of the field lines

• By the spacing of the field lines

• By the color of the field lines

What is the formula for calculating electric field strength?

• Distance divided by charge

• Force divided by charge

• Charge divided by force

• Force divided by distance

What are the units for electric field strength?

• Newtons per meter

• Newtons per coulomb

• Volts per meter

• Coulombs per meter

In a uniform electric field, what happens to a positively charged particle?

• It remains stationary

• It moves towards the negative plate

• It moves in a circular path

• It moves towards the positive plate

How do you calculate the force on a charged particle in an electric field?

• Multiply the charge by the electric field strength

• Divide the charge by the electric field strength

• Subtract the charge from the electric field strength

• Add the charge to the electric field strength

What is the potential difference between two plates if the electric field strength is 1875 volts per meter and the distance is 0.04 meters?

• 0.04 volts

• 1875 volts

• 75 volts

• 47 volts

What is the acceleration of an electron in a uniform electric field if the force is 7.74 x 10^-29 newtons?

• 1.6 x 10^-19 meters per second squared

• 7.74 x 10^-29 meters per second squared

• 9.11 x 10^-31 meters per second squared

• 85 meters per second squared

What is the charge of a particle if it experiences a force of 8.5 newtons in a field of 1150 newtons per coulomb?

• 1.6 x 10^-19 coulombs

• 1150 x 10^-3 coulombs

• 8.5 x 10^-3 coulombs

• 7.4 x 10^-3 coulombs
