) Will the position, velocity, and/or the acceleration vector(s) always be in the direction of the E field at each point for a moving positively charged particle? Explain.
f) How is the answer to e) different (if at all) for a moving negative charge?
e) the position vector for each point will be in the direction of a line joining the point to the origin. Therefore the position vector changes spatially.
Considering there is no external electric field and the only electric field is that of the charge and that the charge is a point charge, there will be no elecctric field at the point where the charge is placed, since classical laws breaks down at microscopic levels.
So only velocity, position and acceleration vectors exists at the point of charge. Since elecctric field is 0, there is no relation between these vectors to the elctric field.
f) Since there os no releation between the velocity, position and acceleration vectors to the elctric field, there is no difference whether it is a positive charge or a negative charge
