A uniform electric field is present in the positive x direction and if the intensity of the field is 5 N/C, then find out the potential difference between two two points A(0, 2) and B(5,3).

Potential drop in moving from (0,2) to (5,0), that is, only in x direction is Ed=25V.

Potential change in moving from (5,0) to (5,3) is zero since the electric field is perpendicular to this direction of movement.

Hence total potential difference between points A and B=25V
