1.	A hollow sphere of radius R/4 is released from the top of a fixed sphere of radius R as shown. The angle theta made by the radius vector at the instant when smaller sphere leaves contact with the bigger sphere is (assume pure rolling of hollow sphere without slipping) cos^(-1)((10)/(10+x)) where 'x' is
