A body of mass \( 200 \, \text{g} \) is tied to a spring of spring constant \( 12.5 \, \text{N/m} \), while the other end of spring is fixed at point O. If the body moves about O in a circular path on a smooth horizontal surface with constant angular speed \( 5 \, \text{rad/s} \). Then the ratio of extension in the spring to its natural length will be:
