A spherical ball of density `rho` and radius` 0.003m` is dropped into a tube containing a viscous fluid up to the 0 cm mark as shown in the figure. Viscosity of the fluid `=1.26N-s//m^(2)` and its density `rho_(L)=(rho)/(2)=1260kg//m^(3)`. Assume that the ball reaches a terminal speed at 10cm mark. The time taken by the ball to travel the distance between the 10cm and 20cm mark is `(g=10m//s^(2))`
