1.	Earth (uniform solid sphere of Mass M Radius rotaes about its North pole - south pole diameter at a constant angular velocity omega. A small block of mass m kept at a colatitude of theta doesn'tslip on earth's surface Then which of the following statements is INCORRECT ?
Answer» Angular MOMENTUM of the BLOCK about centre of the EARTH is conserved Torque of Gravitational force on the block about the centre of the earth is zero Angular velocity of the block about the centre of the earth is `omega sin theta` Angular momentum of the block about the centre of the earth is `mR^(2)omegasin theta` ANSWER :A
