A block of mass m is kept on rough horizontal tum table at a distance r from centre of table. Coefficient of friction between turn table and block is mu. Now turn table starts rotating with uniform angular acceleration alpha. Find angle made by friction force with velocity at the point of slipping,

1.	A block of mass m is kept on rough horizontal tum table at a distance r from centre of table. Coefficient of friction between turn table and block is mu. Now turn table starts rotating with uniform angular acceleration alpha. Find angle made by friction force with velocity at the point of slipping,
