A points start from rest and moves along a circular path with a constant tangential acceleration. After one rotation what is the ratio of radial accelaration and tangential acceleration?

The tangential acceleration of the particle is given by:
v²/r
After one rotation, the point comes back to its initial position. So, its radial acceleration at that point is zero
Therefore, the ratio of the radial acceleration to the tangential acceleration is also zero...
