A coin placed on a rotating turn table just slips if it is placed at a distance of 4 cm from the centre. If the angular velocity of the turn table is doubled it will just slip at a distance of :
A thin uniform rectangular plate of mass 2 kg is placed in X-Y plane as shown in figure. The moment of inertial about x-axis is Ix = 0.2 kg m2 and the moment of inertia about y-axis is Iy = 0.3 kg m2. The radius of gyration of the plate about the axis passing through O and perpendicular to the plane of the plate is
