Which force is a long range force?

Which force is a long range force?

(i) Gravitational force and electrostatic force are long range forces. (ii) Molecule force, weak and strong nuclear forces are short range forces.

What are the long range forces?

For the case of two neutral molecules, a numerical comparison is made of the three types of long-range forces: gravitational, electromagnetic, and weak.

What kind of force is friction?

Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces.

Is electrostatic force a long range force?

We study the interaction forces in atomic nuclei based on our expressions for the electrostatic interaction between spheres of arbitrary radii and charges. Therefore they are so-called long-range-acting forces. For dimensional objects however, it is possible that electrostatic forces be short-range-acting.

Is gravity a long range force?

The strong force, too, operates only on short ranges. But gravity, which theorists believe is carried by particles called gravitons traveling at the speed of light, is a long-range force.

Which force has the shortest range?

the strong nuclear force
We should know that the strong nuclear force has the shortest range among all the four fundamental forces. The range of the strong nuclear force is 10 times shorter in order of magnitude.

Why electric force is short range?

For dimensional objects however, it is possible that electrostatic forces be short-range-acting. A typical example in this regard is the attraction and repulsion force between molecules. These forces are electrostatic in nature and change very fast with distance.

What makes a force a long range force?

A force/field which depends inversely on the square of the distance of the source from the point of interest (like electric field depends on ² 1 / r ², where r is the distance between the the source charge and the test charge) is said to be ‘long range’.

Are there any non elementary forces in physics?

There are also non-elementary contact forces like friction, clearly derived from molecular forces, and which are also short range, due to a complex balancing of electromagnetic forces in atoms and molecules. The basic physics forces from which all else are derived are the ones discussed in the paragraphs above

Why are long range forces carried by zero mass particles?

The basic reason from FT or QFT and equivalent theory is that long range forces or fields are carried by zero mass particles, such as the photon or graviton. Massive force fields like the strong and weak FIELDS decay proportionally to exp (- k m r )/r, i.e., negative exponentially in r as well for m not equal to zero.
