Work is positive when force is in same direction as displacement. So here the direction is X to Y and the force is also from X to Y because Vx>Vy?kuruman said:
Yes, electric field lines point from a region of high potential to a region of low potential. Since the charge is positive, the electric force on it is in the same direction as the electric field.Cicicicici said:

Work done per unit charge by electric field on charge is a measure of the energy transferred to an electric charge as it moves through an electric field. It is represented by the formula W/Q, where W is the work done and Q is the charge.
Work done per unit charge is calculated by dividing the work done on an electric charge by the magnitude of the charge. This gives the amount of energy transferred to the charge per unit of charge.
The unit of measurement for work done per unit charge is joules per coulomb (J/C). This represents the amount of energy transferred to a charge of one coulomb as it moves through an electric field.
Work done per unit charge is directly related to electric potential. The electric potential is the amount of work done per unit charge in bringing a test charge from infinity to a specific point in an electric field. In other words, electric potential is a measure of the work done per unit charge by the electric field on a charge.
Work done per unit charge is important because it helps us understand the strength and direction of an electric field. The magnitude of this quantity gives us an idea of how much energy is transferred to a charge as it moves through the field, and the direction of the quantity tells us the direction in which the electric field is pushing or pulling the charge.
