A positive point charge is released from rest at a distance \( r_{0} \) from a positive line charge with uniform density. The speed (v) of the point charge, as a function of instantaneous distance \( r \) from line charge, is proportional to
(a) \( v \propto \sqrt{\ln \left(\frac{r}{r_{0}}\right)} \)
(b) \( v \propto e^{+\frac{r}{r_{0}}} \)
(c) \( v \propto \ln \left(\frac{r}{r_{0}}\right) \)
(d) \( v \propto\left(\frac{r}{r_{0}}\right) \)
