PhysicsMedium148×since 2002Q7919A small ball of mass M\mathrm{M}M and density ρ\rhoρ is dropped in a viscous liquid of density ρ0\rho_{0}ρ0. After some time, the ball falls with a constant velocity. What is the viscous force on the ball ?AF=Mg(1−ρOρ)\mathrm{F}=\mathrm{Mg}\left(1-\frac{\rho_{\mathrm{O}}}{\rho}\right)F=Mg(1−ρρO)BF=Mg(1+ρPo)\mathrm{F}=\mathrm{Mg}\left(1+\frac{\rho}{P_{o}}\right)F=Mg(1+Poρ)CF=Mg(1+ρoρ)\mathrm{F}=\mathrm{Mg}\left(1+\frac{\rho_{\mathrm{o}}}{\rho}\right)F=Mg(1+ρρo)DF=Mg(1±ρρ0)F=M g\left(1 \pm \rho \rho_{0}\right)F=Mg(1±ρρ0)Check answerSkip
