* Nonuniform Field: The key word here is "nonuniform." A nonuniform electric field means the strength of the field varies from point to point.
* Force Direction: While the field lines point in the same direction, the force acting on the charge will not be constant. The force on the charge is proportional to the electric field strength, so as the charge moves, the force will change.
* Curved Trajectory: Since the force is changing direction, the acceleration of the charge will also change, leading to a curved trajectory. The charge will be deflected towards regions of stronger field strength.
Example: Imagine a point charge placed near a large, positively charged plate. The electric field lines point away from the plate, but the field is stronger closer to the plate. If the charge is released, it will accelerate towards the plate, but its path will be curved because the force pulling it towards the plate is stronger as it gets closer.
In Summary: While the field lines point in the same direction in a nonuniform field, the varying field strength will result in a changing force and therefore a curved trajectory for the charge.
