The tangent to a circle is perpendicular to the radius at the point of tangency. So, triangle OPQ is a right triangle. We are given that OQ = 12 cm and OP = 5 cm (radius of the circle).

Using Pythagoras' theorem, we can find the length of PQ:
PQ^2 = OQ^2 - OP^2 = 12^2 - 5^2
PQ^2 = 144 - 25
PQ^2 = 119

Taking the square root of both sides, we find:
PQ = √119 cm

Therefore, the length of PQ is √119 cm.
