Question
A small test charge is released at rest at a point in an electrostatic field configuration. Will it travel along the field line passing through that point?

Solution
Yes,
If a small test charge is released at rest at a point in an electrostatic field configuration, then it will travel along the field lines passing through the point, only if the field lines are straight. This is because the field lines give the direction of acceleration and not of velocity.
