    the buoyant force acting on the ice cube is 0.119 N

    Explanation:

    given,

    volume of ice cube = 15 cm³ = 15 * 10⁻⁶ m³

    density of ice cube = 917 kg/m³

    density of ethyl alcohol = 811 kg/m³

    buoyant force = ?

    The density of ice is more than ethyl alcohol hence it will sink.

    buoyant force acting on the ice cube = ρ V g

    = 811 * 15 * 10⁻⁶ * 9.81

    =0.119 N

    so, the buoyant force acting on the ice cube is 0.119 N
