A bob of mass `10 kg` is attached to a wire `0.3 m` long. Its breaking stress is `4.8xx10^(7) N//m^(2)`. Then area of cross-section of the wire is `10^(-6) m^(2)`. What is the maximum angular velocity with which it can be rotated in a horizontal circle?
A. `2 "rad"//s`
B. `4 "rad"//s`
C. `6 "rad"//s`
D. `8 "rad"//s`
