Electric Field and Potential Energy Quiz

What is the potential difference between the parallel plates in the setup?

• 100 volts

• 0 volts

• 200 volts

• 50 volts

How is the electric field strength calculated in a uniform field?

• By dividing the potential difference by the distance between the plates

• By multiplying the potential difference by the distance between the plates

• By subtracting the distance from the potential difference

• By adding the potential difference to the distance between the plates

Why is the vertical distance considered irrelevant in this problem?

• Because the electric field strength is constant

• Because the vertical distance is too small to matter

• Because the electric field is non-uniform

• Because the potential energy only depends on horizontal movement

What is the change in potential energy when moving the proton from position one to position two?

• 1.04 * 10^-7 Joules

• 2.08 * 10^-7 Joules

• 5.20 * 10^-7 Joules

• 0 Joules

What is the charge of the proton used in the calculation?

• 1.6 * 10^-18 C

• 3.2 * 10^-18 C

• 3.2 * 10^-19 C

• 1.6 * 10^-19 C
