SUMMARY
The electric potential in a uniform electric field is given as -1000 V at x = -0.900 m and +1400 V at x = +2.00 m. To find the electric field strength (E_{x}), the relationship E = -dV/dx is utilized, where dV is the change in electric potential and dx is the change in position. The slope of the potential function indicates the magnitude and direction of the electric field, which runs from higher to lower potential. The correct interpretation of the distance (d) in the equation V = Ed is crucial, as it represents the separation between the two points rather than a specific position.
