Question

A positive point charge is released from rest at a distance r₀ 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 :-

$v \propto \left( {{r \over {{r_0}}}} \right)$

$v \propto \ln \left( {{r \over {{r_0}}}} \right)$

$v \propto {e^{ + r/{r_0}}}$

$v \propto \sqrt {\ln \left( {{r \over {{r_0}}}} \right)} $
