Properties of Matter question

2024 · 6 Apr · Shift 1 · Q77

JEE MainPhysicsProperties of MatterMCQ+4 / −1
A small ball of mass mmm and density ρ\rhoρ is dropped in a viscous liquid of density ρ0\rho_0ρ0​. After sometime, the ball falls with constant velocity. The viscous force on the ball is :
  1. A
    mg(1−ρ0ρ)m g\left(1-\frac{\rho_0}{\rho}\right)mg(1−ρρ0​​)
  2. B
    mg(ρ0ρ−1)m g\left(\frac{\rho_0}{\rho}-1\right)mg(ρρ0​​−1)
  3. C
    mg(1−ρρ0)m g\left(1-\rho \rho_0\right)mg(1−ρρ0​)
  4. D
    mg(1+ρρ0)m g\left(1+\frac{\rho}{\rho_0}\right)mg(1+ρ0​ρ​)
