The terminal velocity of a steel ball of radius r and density \(\rho\) falling through an oil column of density \(\sigma\) and viscosity \(\eta\) is

Two capillary tubes of radii in the ratio $1:2$ are dipped in the same liquid. The ratio of heights through which the liquid will rise in the tubes is

The relative viscosity of blood $\left(\frac{\eta}{\eta_{water}}\right)$ is constant between

A solid sphere of volume \(V\) experiences a viscous force \(F\) when descending with a speed \(v\) in a liquid. If another solid sphere of volume \(27V\) descends with the same speed \(v\) in the same liquid, it experiences a viscous force

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

After terminal velocity is reached, the acceleration of a body falling through a fluid is

Two capillary tubes A and B of diameter 1 mm and 2 mm respectively are dipped vertically in a liquid. If the capillary rise in A is 6 cm, then the capillary rise in B is
