1.	One end of a long iron chain of linear mass density λ is fixed to a sphere of mass m and specific density 13 while the other end is free. The sphere along with the chain is immersed in a deep lake. If specific density of iron is 7. If the height h above the bed of the lake at which the sphere will float in equilibrium is xm3λ. then the value of x is (Assume that the part of the chain lying on the bottom of the lake exerts negligible force on the upper part of the chain)
Answer» One end of a long iron chain of linear mass density $λ$ is fixed to a sphere of mass $m$ and specific density $\frac{1}{3}$ while the other end is free. The sphere along with the chain is immersed in a deep lake. If specific density of iron is 7. If the height $h$ above the bed of the lake at which the sphere will float in equilibrium is $\frac{x m}{3 λ}$ . then the value of $x$ is (Assume that the part of the chain lying on the bottom of the lake exerts negligible force on the upper part of the chain)
