A cube with a mass `= 20 g` wettable water floats on the surface of water. Each face of the cube is `alpha = 3 cm` long. Surface tension of water is `70 dyn//cm`. The distance of the lower face of the cube from the surface of water is (`g= 980 cm s^(-12)`)

A cube with a mass m = 20g wettable by water floats on the surface of water. Each face of the cube is a = 3cm long. Surface tension of water is 70 dyne/cm. The distance of the lower face of the cube from the surface of water is (x+0.3)cm. Find x. (g = 980cm/ s^2 )

A cube with mass m = 20 g wettable by wter floats on the surface of water. Each face of the cube is 3 cm long. If the distance (cm) between the lower face of the cube and the surface of the water in cotact with the cube is 4.6 lambda cm , then find lambda ? [ S.T of water alpha = 30 dyn//cm , assume contact angle to be theta = 0^(@) ]

If surface tension of water is 70 dyn cm^-1 , what is its value in S.I.?

A cube with mass m completely wettable by water floats on the surface of water each side of the cube is a what is the distance h between the lower face of cube and the surface of the water if surafce tension is S. Take densities of water as rho_(w) take angle of contact is zero.
