A solid sphere of radius R made of a material of bulk modulus K is surrounded by a liquid in a cylindrical container. A massless pistion of area A floats on the surface of the liquid. When a mass M is placed on the piston to compress the liquid the fractional change in the radius of the sphere, `deltaR//R`, is .............
A. `(Mg)/(BA)`
B. `(Mg)/(3BA)`
C. `(3Mg)/(4BA)`
D. `(Mg)/(4BAR)`
