Dragging force depends upon
Correct answer: D. All
- A. Velocity of spherical body
- B. Radius
- C. Coefficient of viscosity
- D. All
Explanation
The dragging force, or drag force, experienced by an object moving through a fluid depends on various factors, including the velocity of the object, its radius (or size), and the coefficient of viscosity of the fluid. Therefore, all the options listed contribute to the determination of the drag force.

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.
