A small block of mass \( 100 \, \text{g} \) is tied to a spring of spring constant \( 7.5 \, \text{N/m} \) and length \( 20 \, \text{cm} \). The other end of spring is fixed at a particular point A. If the block moves in a circular path on a smooth horizontal surface with constant angular velocity \( 5 \, \text{rad/s} \) about point A, then tension in the spring is:
