Question

Whenever the surfaces in contact tend to move or move with respect to each other, the force of friction comes into play
(a) only if the objects are solid.
(b) only if one of the two objects is liquid.
(c) only if one of the two objects is gaseous.
(d) irrespective of whether the objects are solid, liquid or gaseous.

Answer 1

Answer:

The answer is d) irrespective of whether the objects are solid,liquid or gaseous.

Explanation:

Friction occurs irrespective of state of the matter. Friction provided by liquids and gases are known as fluid friction.

Answer 2

Answer:

The correct answer is D) Irrespective of whether the objects are solid, liquid or gaseous.

Explanation:

From the above question,

They have given :

         Friction is a force that occurs whenever two surfaces come into contact and move or attempt to move relative to each other. This force is present regardless of whether the objects are solid, liquid, or gaseous. It is the interaction between the two surfaces that causes friction.\

       Friction is the force that resists motion when two surfaces are in contact. It is the reaction force that opposes the motion of the two surfaces.

       The force of friction depends on the types of surfaces in contact, the area of contact between the surfaces, and the amount of pressure applied. Friction is present regardless of the type of material, whether it is solid, liquid, or gaseous.
