What is the terminal velocity of a rain drop of radius ? [Note that the coefficient of viscosity of air is , density of water is . Use and density of air can be neglected in comparison with density of water]
- A
- B
- C
- D
Answer & Solution
Correct Answer
(A)
Step-by-step Solution
Detailed explanation
Terminal velocity is a steady speed achieved by an object freely falling through a viscous gas or liquid. At terminal velocity, the viscous force on the object is equal to the weight of the object minus the buoyance force. The density of air can be assumed negligible.…
