Physics - SHM Question with Solution | TestHub

Four identical massless springs, two massless pulleys and a block of mass $m$ are connected as shown and system is kept in vertical plane. Initially the system is in equilibrium. Now the block is slightly displaced from equilibrium position along a vertical line and then released. If the time period (in sec) of small oscillation of the block is T then find the value of (10T + 0.2) ? Given that$\mathrm{m}=6.6\mathrm{kg}$ and $\mathrm{k}=70\mathrm{N}/\mathrm{m}$. (take $\pi =3.14$ )
