What is the range of electromagnetic force in physics class 11?

Electromagnetic force is acts between charged particles in nature and combination of electrical and magnetic force. So range of electromagnetic force is infinite because universe is not limited.

Is electromagnetic force long range?

The electromagnetic force causes electric and magnetic effects such as the repulsion between like electrical charges or the interaction of bar magnets. It is long-ranged but much weaker than the strong force. It can be attractive or repulsive and acts only between pieces of matter carrying an electrical charge.

Does electromagnetism have infinite range?

In contrast to the nuclear forces, both the electromagnetic force and gravity have effectively infinite range* and die off in strength as 1/r2. The electromagnetic force due to an electric quadrupole dies off even more rapidly, as 1/r4, because the negative charges do such a good job of canceling the positive charges.

Does electromagnetic force have a short range?

The electromagnetic force is a force of infinite range which obeys the inverse square law, and is of the same form as the gravity force. The electromagnetic force holds atoms and molecules together.

What is electromagnetic force?

The fundamental force associated with electric and magnetic fields. The electromagnetic force is carried by the photon and is responsible for atomic structure, chemical reactions, the attractive and repulsive forces associated with electrical charge and magnetism, and all other electromagnetic phenomena.

Which force is the longest range force?

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

Which force is long range force?

Long range force A force that does not need contact between objects to exist. One example is the gravitational force (weight).

Which is the long range force?

(i) Gravitational force and electrostatic force are long range forces.

Which force has longest range?

gravitational force
Longest range force is gravitational force and nuclear force is shortest range force.

Which two forces have a universal range?

Both electromagnetism and gravity have infinite range.

What is the strongest force on earth?

The strong nuclear force
The strong nuclear force, also called the strong nuclear interaction, is the strongest of the four fundamental forces of nature. It’s 6 thousand trillion trillion trillion (that’s 39 zeroes after 6!) times stronger than the force of gravity, according to the HyperPhysics website.

Which force has 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.

What is the range of electromagnetic force?

Answer Wiki. The range of electromagnetic force is considered to be infinite. The electromagnetic force is mediated by exchange of photon, which is massless. (There have been numerous attempts to measure the mass of photon and it has been found to be consistent with zero).

What is the value of K for electromagnetic force?

As with all forces, electromagnetic force is measured in Newtons (N). The constant k has a specific value, 9 × 10 9 N m 2 / C 2. Charge is measured in coulombs (C), and you input the sign of the charge (+ or −) along with the strength, so the equation has a positive value for repulsion and a negative one for attraction.

What do you mean by electromagnetism?

Electromagnetism. Electromagnetism is a branch of Physics, that deals with the electromagnetic force that occurs between electrically charged particles. The electromagnetic force is one of the four fundamental forces and exhibits electromagnetic fields such as magnetic fields, electric fields, and light. It is the basic reason electrons bound

How do you find the force of electromagnetic repulsion?

As with all forces, electromagnetic force is measured in Newtons (N). The constant k has a specific value, 9 × 10 9 N m 2 / C 2 . Charge is measured in coulombs (C), and you input the sign of the charge (+ or −) along with the strength, so the equation has a positive value for repulsion and a negative one for attraction.
