A particle of mass m is fixed to one end of a light spring of force constant k and unstretched length l.
The system is rotated about the other end of the spring with an angular velocity 
in gravity free space. The increase in length of the spring will be
A
B
C
D
None of these
Text Solution
Verified by ExpertsThe correct answer is:
B
Let 
be the increase in the length of the spring, then the particle moves along a circular path
of radius 
.
