Question
A spherical solid ball of volume V is made of a matrial of density ρ1. It is falling through a liquid of density ρ1(ρ2 < ρ1). Assume that the liquid applies a visous forcw of its speed v,i.e., Fviscous = - kv(k > 0) The terminal speed of the ballis
Options
A.
B.
C.
D.
Solution
he condition for terminal speed (Vt) is Weight = Buoyant force + Viscous force
∴ Vρ1g = Vρ1g + kvt2
vt =
∴ Vρ1g = Vρ1g + kvt2
vt =
