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?
[Breaking stress of wire= 4.8 x 10 7 N m -2 and area of cross-section of the wire= 10 -2 cm 2 ]
