A charged particle is free to move in an electric field. Will it always move along an electric field?                                          

Answer:

                The tangent at any point to the line of force gives the direction of electric field and hence of force on a charge at that point. If the charged particle starts from rest, it will move along the line of force. If it is in motion and moves initially at an angle with the line of force, then resultant path is not along the line of force.
