An electron moves between two points X and Y in a uniform electric field, as shown. [Figure showing a uniform electric field with points X and Y, where the line XY is at an angle of 60° to the field direction] The distance between X and Y is 4.0 cm and the line XY is at an angle of 60° to the direction of the field. The field exerts the only force on the electron. The field strength is 100 N C⁻¹. What is the change in the kinetic energy of the electron as it moves from X to Y?
