Answer:
Viscosity of water is 0.91 centi poise at 20 C. (0.91×10-2 poise). wrong data for viscosity of water is given in the question. For the answer I am using 8×10-3 poise for viscosity of water.
terminal velocity is given by
r is radius of sphere, ρ is density of aluminium, σ is density of water and η is viscosity of water. Hence the 4.6 m/s is the correct answer.
