1.	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)/(AK)`B. `(mg)/(3AK)`C. `(mg)/(A)`D. `(3mg)/(AK)`
Answer» Correct Answer - B `(DeltaV)/(V) = (F)/(AK) = (mg)/(AK), (Delta R)/(R) = (1)/(3) (Delta V)/(V)`
