Upthrust = Weight of Fluid Displaced
Hence , mass of water displaced = density * volume = (1000) * (4/3 pi (1/100)^3)
Hence weight displaced = mass * g = (1000) * (4/3 pi (1/100)^3) * 9.81 = Upthrust
Coefficient of visc needed only for drag force....
Upthrust + Drag = Weight of ball
[at terminal velocity]
