A mass `'m'` is attached with rods as shown in Fig. This mass is slightly stretched and released. Find out whether the motion of mass is `S.H.M`. If yes then find out the time period.

`k_(eq)=(k_(1)k_(2))/(k_(1)+k_(2)) T=2pisqrt((m)/(k_(eq)))=2pisqrt((m(k_(1)+k_(2)))/(k_(1)k_(2)))`
where `k_(1)=(A_(1)y_(1))/(l_(1))` and `k_(2)=(A_(2)y_(2))/(l_(2))`
