For a circle with centre $O$ and radius 5 cm , which of the following statements is true?\ P : Distance between every pair of parallel tangents is 5 cm .\ Q: Distance between every pair of parallel tangents is 10 cm .\ R : Distance between every pair of parallel tangents must be between 5 cm and 10 cm .\ S : There does not exist a point outside the circle from where length of tangent is 5 cm .\
