Let the maximum displacement of block is hExtension in spring2=xExrension in spring1=yNow for a moment suppose there is only spring2Then, when block is released then by work energy theorem1/2kx²=mgxx=2mg/k........(i)Similarly we can find out y which will be 2x...... (force=2T)Now by work energy theorem for whole system½kx²+½ky²=mgh½kx²+½k(4x²)=mghPutting x=2mg/kh=10mg/kThus X=2
