An electric charge of 2.10-3C at a point X in an electric field had electric potential energy of 4.10-2 J. It was moved to another point Y where it’s potential energy was 6.10-2J. What is the potential difference between X and Y and the electric field strength if the points X and Y and seperated by distance 0.25m?
ΔEPE = 0.0610J - 0.0410J = 0.0200 J, so
a) ΔVxy =
b) E =
assuming the motion was parallel to the field.
