Solving the equation for r:
With the first equations, we can establish some limits for V:
With the lowest value for r (r=0):
With the highest value for r (r=9.5x10^-3)
According to the radius range, velocity can be between 0 and 3.61x10^-2
It is also necessary to check the domain of the function considering it is a square root. The argument of an square root cannot be less than 0. Then:
This is the same limit for velocity obtained before. Then, we can say for velocity that:
