Item 10 refers to the following diagram of a small ball bearing falling from rest in a viscous liquid. The forces acting on the ball bearing are its weight, W, viscous drag, F, and upthrust, U.
When terminal velocity is achieved, which of the following conditions is satisfied?
- (A)
F + U > W - (B)
F + U < W - (C)
F + U = W - (D)
F + U + W = 0
