A spherical ball of diameter 1 {cm} and density 5 \times 10^{3} {kg} {m}^{-3} is dropped gently in a large tank containing viscous liquid of density 3 \times 10^{3} {kg} {m}^{-3} and coefficient of viscosity 0.1 {Ns} {m}^{-2}. The distance, the ball moves in 1 s after attaining terminal velocity is (g=10 {ms}^{-2})
