Do charges released from rest always move along electric field lines; i.e., does the charge stay on the E field line at which it started?
b) Based on your answer to a), would charges released with an initial velocity always move along electric field lines?
c) Using kinematic quantities like position, velocity, and acceleration as well as the concept of a force to describe the general character of the motion of a [+] charge in motion near a single [+] charge.
d) Describe the types of motion possible for a [-] charge placed in motion near a single [+] charge. Based on your answer, could you produce a motion which is a perfect closed circle?
e) 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?
