Question

A cube with edge length L = 0.28 m and density ρc = 3.2×103 kg/m3 is exactly half submerged in a liquid of density ρl = 0.95×103 kg/m3, as shown in the figure. The cube is suspended by a taut string and is in static equilibrium.

b) Enter an expression for the magnitude of the buoyant force acting on the cube, in terms of ρlL, and g

FB = 

c) Enter an expression for the magnitude of the tension in the string, in terms of the defined quantities and g

T =
