A body of mass m=10 kg is attached to one end of a wire of length 0.3 m. What is the maximum angular speed (in rad $s^{-1}$ ) with which it can be rotated about its other end in a space station without breaking the wire……….Rad / s [Breaking stress of wire = 4.8 x  ${10}^{7}N{m}^{-2}$  and area of cross-section of the wire =  ${10}^{-2}c{m}^2$].
