In picture 1, you can observe the motion of a positive
charge q, which is launched with an initial velocity Vx,
inside an electric field
generated by an immobile charge Q. In picture 2, the graphs (r-t) or (F-r) are indicated.
try different values for the initial velocity
(0.1, 0.2, ... 1.4)
and observe the motion
Question: a) What is the Q charge's type? b) Describe
the type of motion in all cases.
Exercise: Fot the case of circular motion, calculate:
a) the period of the motion, b) the force between the charges
(hint:use the time indicated in picture 1 and the distance from the
