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

The potential difference (ΔV) in an electric field (E) over a distance (d) is given by ΔV = Ed. Here, E = 50 N/C, and d = 1.0 m. Since the field is directed east and we're moving west (against the field direction), the potential increases, so ΔV = 50 N/C * 1.0 m = 50 V. Therefore, the potential at the point 1.0 m west is 80 V + 50 V = 130 V.
