EAMCET Engineering 2004 Solved Paper

A thin uniform square lamina of side a is placed in the xy-plane with its sides parallel to X and Y-axes and with its centre coinciding with origin. Its moment of inertia about an axis passing through a point on the Y-axis at a distance Y=2a and parallel to X-axis is equal to its moment of inertia about an axis passing through a point on the X-axis at a distance x=d and perpendicular to xy-plane. Then value of d is
