Which statement about electric charges in a uniform electric field is not correct?

1. AElectric charges of the same magnitude, whether positive or negative, experience the same magnitude of force when placed in the same uniform electric field.
2. BThe direction of the force on a positive charge placed in a uniform electric field is independent of the magnitude of the charge.
3. CThe magnitude of the force on a positive charge placed in a uniform electric field is proportional to the magnitude of the electric field strength.
4. DThe work done to move a positive charge a certain distance in a uniform electric field is independent of the direction of the movement.
