In a various form of matter the constituent particles are held together with different types of forces. The extent of forces depends on the nature of the substances. The forces operating in solid xenon are________

Find the force exerted by the water on a 2m^2 plane surface of a large stone placed at the bottom of a sea 500 m deep. Does the force depend on the orientation of the surface? Neglect the size of the stone in comparison to the depth of the sea.

Assertion: If an object is submerged in fluid at rest, the fluid exerts a force on its surface. Reason: The force exerted by the fluid at rest has to be parallel to the surface in contact with it.

Surface tension of a liquid is a molecular phenomenon of liquids involving the force of cohesion along the liquid molecules. It is scalar quantity and is numerically equal to the surface energy. Numerically, it is proved that the potential soluble salts and surface active substance. Sparingly soluble salts and surface active substances decrease the surface tension of the liquid. However, the fairly soluble solutes increase the surface tension of the liquid. Surface tension of a liquid is independent of surface area but it depends on the intermolecular forces and the temperature. Surface tension of a liquid does not depend on :
