Motion in A Plane

Question: A weightless thread can support tension upto 30 N. A stone of mass 0.5 kg is tied to it and is revolved in a circular path of radius 2 m in a vertical plane. If \[g = 10m/{s^2}\], then the maximum angular velocity of the stone will be

1) \[5\,\,rad/s\]

2) \[\sqrt {30} \,rad/s\]

3) \[\sqrt {60} \,rad/s\]

4) \[10\,rad/s\]
