A copper piece of mas 10 g is suspended by a vertical spring. The sprig elongates 1 cm over its natural lenngth to keep the piece in equilibrium. A beaker containing water is now placed below the piece so as to immerse the piece completely in water. Find the elongation of the spring. Density of copper =9000 kgm^-3. `Take g=10ms^-2`
