A positive test charge q is released near a positive fixed charge Q.

I am not sure if am suppose to consider this charge q, released in the space where there is no friction, or if it is released where there is friction... am I too far from the answer? Because I would assume that it will be in decreasing acceleration. Very confuse with all this topic.

Thanks!

I would assume there is no friction in this question. Usually intro physics questions will specify EVERYTHING you need to solve it. Since there is no $\mu$, I would guess that you should only consider the electric force on the test particle.

that's what i thought. Thank you very much!
