what is the angle between linear acceleration vector and angular acceleration vector

They are perpendicular to each other. Angular acceleration is a scalar multiple of torque, which is to say that they always point in the same direction. Torque is always perpendicular to the radius vector because it is the cross product of the radius and a torque, and thus must be perpendicular to both.
The important part to remember is that the torque and acceleration don’t point in the direction we ‘feel’ that they should. A force causes something to accelerate in the direction the vector points. Simple. The torque vector though, points along the axis of rotation, with the sense of the body’s rotation given by the right hand rule.....
