1.	A spherical body of radius R is allowed to roll down on an incline with out slipping and it recheas with a speed v_(0) at the bottom. The incline is then made smooth bywaxing and the body is allowed top slide without rolling and now the speed attained is (5)/(4)v_(0) The radius of gyration of the body about an axis passing through the centre is
