Stoke's law is applicable if body has _ shape
Correct answer: C. spherical
- A. rough
- B. square
- C. spherical
- D. all of these
Explanation
Stoke's law is primarily applicable to objects that have a spherical shape. This law describes the drag force experienced by a spherical object moving through a viscous fluid and is particularly accurate for small spheres moving at low speeds

About Fluid Dynamics
Fluid flow is described through speed, pressure and density, including steady flow and the equation of continuity for conserving mass. Bernoulli's equation relates pressure, speed and height, while fluid drag and terminal velocity explain why a falling object eventually moves at constant speed when drag balances its weight.
