Question

Easy

Solving time: 2 mins

In the reported figure, two bodies $A$ and $B$ of masses $200 g$ and $800 g$ are attached with the system of springs. Springs are kept in a stretched position with some extension when the system is released. The horizontal surface is assumed to be frictionless. The angular frequency will be $rad / s$ when $k = 20$ $N / m .$

μ = \frac{m _{1} m _{2}}{m _{1} + m _{2}} \Rightarrow \frac{200 \times 800}{200 + 800} = 160 g = 0.16 kg K_{e q} = \frac{k _{1} k _{2}}{k _{1} + k _{2}} = \frac{4 k \times k}{4 k + k} = \frac{4}{5} k = \frac{4}{5} \times 20 = 16 \frac{N}{m} ω = \frac{K _{e q}}{μ} = \frac{16}{0.16} = 10
