A symmetric lamina of mass M conists of a square shape with a semicircular section over of the edge of the square as shown in figure. The side of the square is 2a. The moment of inertia of the lamina about an axis through its centre of mass and perpendicular to the plane is 1.6 Ma². The moment of inertia of the lamina about the tangent AB in the plane of the lamina is  ………….
