Geodesic curvature of a curve of a vector field

Let V be a vector field in a surface in a Euclidean apace of three dimensions. PAN has studied the normal curvature of the vector field V with generalization obtained by the author. The object of the present note is to define the geodesic curvature of the curve of the vector field and obtain some properties. As a special case when the curves of the vector field V form an orthogonal net of co ordinate curves, these geodesic curvatures have the known form.
