Since the orientation of the dipolar moment vector is varying constantly due to the molecular movement, the average dipolar moment is zero, which does not prevent the existence of these interactions between momentary dipoles. Starting with two instantaneous dipoles, they will be oriented to reach a...

Force is everywhere and it comes in a variety of sizes, directions, and type. We can define Force as the push or pull of an object. Learn Force definition, unit & types of Force with solved examples.
Vector Notation of a Force (Rectangular Representation of a Force)F=FλF=FλWhere λ is a unit vector. There are two cases in determining λ; by direction cosines and by the coordinates of any two points on the line of action of the force....
