2. A particle of mass m is fixed to one end of a masslessspring of spring constant k and natural length lo. Thesystem is rotated about the other end of the spring witlan angular velocity Ď, in gravity-free space. The finallength of spring is2 |

Answer» Let x= increase in lenght of string Then the particle moves along the circular path.of radius (l+x) and the spring force =kx=centripatal force Therefore mω²(l+x)=kx or x=mω²(l+x)/k-mω² wrong answer |
