A small but heavy block of mass 10 kg is attached to a wire 0.3m long. Its breaking stress is 4.8 × 107 N/m2. The area of cross section of the wire is 10–6 m2. The maximum angular velocity with which the block can be rotated in the horizontal circle is
- 4 rad/s
- 8 rad/s
- 10 rad/s
- 32 rad/s
Answer
