Consider a uniform horizontal electric field of 50 NC direct

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?

Solution

According to the question we need to find the value of the potential.

Delta (v) = -50 * 1.00 m * cos 180 = 50.0 V

V(B)= 50.0 V + 80.0 V = 130.0 V ====================ANSWER)
