Two blocks of mass ${\mathrm{m}}_1=10 \mathrm{kg}$ and ${\mathrm{m}}_2=20 \mathrm{kg}$ are placed on a fixed inclined surface making an angle $\mathrm{\theta }=37°$ with horizontal. One end of a light spring of spring constant $\mathrm{K} = 100 \mathrm{N}/\mathrm{m}$ is free and other end is connected to a support S rigidly fixed to inclined surface. The coefficient of friction between block of mass m₁ and inclined plane is ${\mathrm{\mu }}_1= 0.5$ and that between block of mass m₂ and inclined plane is ${\mathrm{\mu }}_2=1$. At time t = 0 both blocks are released at rest from shown position. (Take $\mathrm{g}=10 \mathrm{m}/{\mathrm{s}}^2$)
