A body of mass $\displaystyle m=10 \mathrm{~kg}$ is attached to one end of a wire of length $\displaystyle 0.3$ m . The maximum angular speed (in $\displaystyle \mathrm{rad} \mathrm{s}^{-1}$ ) with which it can be rotated about its other end in space station is (Breaking stress of wire $\displaystyle =4.8 \times 10^7 \mathrm{Nm}^{-2}$ and area of cross-section of the wire $\displaystyle =10^{-2} \mathrm{~cm}^2$ ) is :
