In electromagnetism, an electric field is induced between two oppositely charged parallel plates. This electric field is a consequence of the difference of the potential energy of the plates and the distance between them. The equation is E =V/d, where E is the electric field in volts/m or Joules, V is the voltage of the potential difference in volts, and d is the distance between the plates in meters.

First, we substitute the distance through the distance formula

d = √[(x2-x1)^2+(y2-y1)^2]
d = √[(3-0)^2+(4-0)^2]
d = 5 meters

Substituting the values:
E = V/d
12 = V/5
V = 60 volts
