Question

The pressure exerted by solids is a little different from that of fluids as in the case of solids, due to
(A) Tight interactions of atoms/molecules
(B) Lose interactions of atoms/molecules
(C) Medium interactions of atoms/molecules
(D) This statement is incorrect

Answer 1

In a substance, the atoms/molecules are held together by the means of intermolecular/interatomic forces. In the gases this force is least and highest in the solids this gives them their characteristic properties of flow thus gases and liquid can flow but solid remains rigid.

Complete step-by-step answer:
We know that fluid particles have less intermolecular/interatomic forces of attraction as compared to solids so they are free to move in any direction so they can exert pressure.
But in a solid substance, the subatomic particles are tightly bound with each other so they can't exert pressure like fluids.

Therefore the correct answer is (A) Tight interactions of atoms/molecules

Additional Information:
The net normal force exerted by a fluid (both liquid and gas) at rest on a surface in contact with it is known as fluid thrust. The pressure in a liquid depends on the following factors, the depth of the container in which the liquid is filled (measured vertically from the liquid surface), the density of the liquid (for ideal fluid), the acceleration due to gravity at that point of observation. Solid placed on a flat surface applies a normal contact force which is equal to its weight. The pressure of the solid on the surface depends on the area of contact between the two surfaces. As pressure is force per unit volume.

Note:
In the given question option (B) and (C) are incorrect as loose intermolecular/interatomic forces of attraction interaction are present in gases and moderate. intermolecular/interatomic forces of attraction are present in liquids.
