The value of the line integral ∮F . rds , where C is a circle of radius units is ________
Here, F ( x, y ) = yî + 2xĵ and r̂ is the UNIT tangent vector on the curve C at an arc length s from a reference point on the curve î and î are the basis vectors in the x – y Cartesian reference. In evaluating the line integral, the curve has to be traversed in the counterclockwise direction.
