A ball is descending at terminal speed in still air. The forces acting on the ball are upthrust, viscous drag and weight. What is the sequence of these three forces in order of increasing magnitude?
- Aupthrust $\rightarrow$ viscous drag $\rightarrow$ weight
- Bviscous drag $\rightarrow$ upthrust $\rightarrow$ weight
- Cviscous drag $\rightarrow$ weight $\rightarrow$ upthrust
- Dweight $\rightarrow$ upthrust $\rightarrow$ viscous drag
