Newton's second law allows finding the answer for the positive direction in circular motion is:
Newton's second law is stable that the net force is proportional to the product of the mass and the acceleration of the bodies, this law is valid for all linear and rotational movements.
F = m a
Where the bold letters indicate vectors, F is the force, m the mass and the acceleration.
Newton's second law the direction of the net force is the same direction of the acceleration, in the case of circular motion the acceleration is directed towards the center of the circle in a radial direction.
Consequently this is the direction of the resultant force is towards the center of the circle and this is the positive direction of motion.
In conclusion using Newton's second law we can find the positive direction in the circular motion is:
