A mass m can rotate with angular velocity w1 on a smooth horizontal table being attached to a spring whose other end having passes through a hole in the table, supports another mass m.This other mass turns around as a conical pendulum with angular velocity w2. if l1 and l2 are the lengths of the string on and below table then
a)l1:l2=w1^2:w2^2
b)l1:l2=w2^2:w1^2
c)l1:l2=w1:w2
d0 none
