A metallic cube of mass ‘m’ is suspended by a string. Area of each face is ‘A’. If p be the hydrostatic pressure on the bottom face of the cube, then

• A

  then tension in the string is mg

• B

  buoyant force acting on the cube is pA.

• C

  buoyant force acting on the cube is less than pA.

• D

  buoyant force acting on the cube is (T-pA) where T is the tension in the string.
