A spherical ball is dropped in a long column of a highly viscous liquid. The curve in the graph shown, which represents the speed of the ball \((v)\) as a function of time \((t)\) is
- A \(B\)
- B \(C\)
- C \(D\)
- D \(A\)
Answer & Solution
Correct Answer
(A) \(B\)
Step-by-step Solution
Detailed explanation
Initially speed is zero, then increases \& after some time it becomes constant. Acceleration (slope of \(v / t\) curve) of ball first decreases and after some time it becomes zero.
