Does a positive test charge follows along the path of electric field lines if it is free to do so? I mean the trajectory of the charge is along the electric field lines and the field lines are not necessarily straight.
No. The positive test charge feels a force due to the field vector at that point. The charge's position gets updated and then feels another force at the new point, and so on.Mausam said:Does a positive test charge follows along the path of electric field lines if it is free to do so?

Electric field lines are a visual representation of the direction and strength of an electric field at different points in space. They are imaginary lines that show the path a positive test charge would take if placed in the electric field.
Electric field lines are drawn by placing a positive test charge at different points in the electric field and then drawing lines in the direction of the force that the charge would experience at that point. The closer the lines are together, the stronger the electric field is at that point.
For a positive point charge, electric field lines radiate outwards in all directions, with the highest concentration of lines near the charge. This represents the strong electric field that is created by a positive charge.
No, electric field lines do not always start and end on charges. In the case of a uniform electric field, the lines will be parallel and evenly spaced, with no starting or ending points. However, for a non-uniform electric field, the lines will start and end on charges.
The density of electric field lines is a visual representation of the strength of the electric field. The closer the lines are together, the stronger the electric field is at that point. Similarly, the further apart the lines are, the weaker the electric field is at that point.
