Question

    A metal ball of volume 0.02 m³ is immersed fully in

    water. Find buoyant force. (Take g=10 m/s2, ρ = 1000 kg/m3)
    A 100 N Correct Answer Incorrect Answer
    B 200 N Correct Answer Incorrect Answer
    C 300 N Correct Answer Incorrect Answer
    D 400 N Correct Answer Incorrect Answer

    Solution

    The buoyant force is given by  Fb=  ρgV , where V is the volume of the displaced fluid. So, Fb = 1000 x 10 x 0.02 = 200 N
