Consider a uniform horizontal electric field of 50 N/C directed toward the east. If the electric potential at a given point in the field is 80 V, what is the potential at a point 1.0 m directly east of
The point?
A) 30 V
B) 15 V
C) 130 V
D) 90 V

The potential difference (ΔV) in an electric field (E) over a distance (d) is given by ΔV = -E*d. Here, E = 50 N/C, and d = 1.0 m. Since the field is directed east and we're moving east, ΔV = -50 V. Therefore, the new potential is 80 V - 50 V = 30 V.
