A uniform rod of length l and mass m is free to rotate in a vertical plane about A as shown in Fig. The rod initially in horizontal position is released. The initial angular acceleration of the rod will be

The angle turned by a body undergoing circular motion depends on time as θ=θ0+θ1t+θ2r^2. Then the angular acceleration of the body is
