1.

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 ω, 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
