Question

Quizplus · Accepted Answer

The potential difference between two points is given by the difference in potential at those points. In this case, V_a is equal to the potential at point S1 minus the potential at point U1B0, and V_b is equal to the potential at point S1 minus the potential at point U1B0. Since the potential at point U1B0 is the same in both cases, the potential difference between V_a and V_b is equal to the potential difference between points S1 and S1, which is 0. Therefore, the potential difference V_a − V_b is equal to 0, or in other words, there is no potential difference between these two points. The correct answer is B) +5.0 V, which is not listed in the choices.
