A solid sphere of radius r made of a soft material of bulk modulus K is surrounded by a liquid in a cylindrical container. A massless piston of the area A floats on the surface of the liquid, covering an entire cross-section of the cylindrical container. When a mass M is placed on the surface of the piston to compress the liquid, the fractional decrement in the radius of the sphere is MgαAB. Then the value of α is
