A thin uniform rectangular plate of mass 2 kg is placed X - Y plane as shown in figure . The moment of intertia about x - axis is `I_(x) = 0.2 kg m^(2)` and the moment of inertia about y - axis is `I_(y) = 0.3 kg m^(2)` .The radius of gyration of the plate about the axis passing throught O and perpendicular to the plane of the plate is .
