Final answer:
The potential difference between points A and B, or the voltage, can be found by multiplying the electric field magnitude with the distance between the points.
Step-by-step explanation:
The potential difference between points A and B, also known as the voltage, can be found by multiplying the electric field magnitude with the distance between the points. Given that the electric field magnitude is 100 N/C and the distance between A and B is d, the potential difference is VAB = 100d volts.
