The value of the line integral ∮C F.T ds, where C is a circle of radius 4/√π units is ________. Here, F(x,y) = y i + 2x j and T is the UNIT tangent vector on the curve C at an arc length s from a reference point on the curve. i and j are the basis vectors in the x-y Cartesian reference. In evaluating the line integral, the curve has to be traversed in the counter-clockwise direction.
