Question

Fluid friction depends upon:

• A. Speed of the object in the fluid.
• B. The shape of the object moving in the fluid
• C. Nature of fluids in which object is moving.
• D. All of the above

Answer 1

The correct option is D

All of the above

Fluid friction on an object moving in a fluid depends upon :

1. Speed of the object in the fluid: the object moves faster in a fluid, greater the fluid friction acting on it.
2. Shape of the object moving in the fluid: If an object is a board, it gives more surface area for the friction to act on.
3. Nature of the fluids in which the object is moving: An object experiences a different amount of friction in different fluids. For example, an object moving at a certain speed experiences greater friction in honey than that experienced in the water.

So, all the options are the correct answer, and hence the correct option for this question is option (d).
