The attractive force between the electrons and the nucleus is called the electric force . Experiments have shown that the electric force between two objects is proportional to the inverse square of the distance between the two objects.
What is the force between electrons called?
The electromagnetic force , also called the Lorentz force, acts between charged particles, like negatively charged electrons and positively charged protons. Opposite charges attract one another, while like charges repel. The greater the charge, the greater the force.
How do you find the electric force between two electrons?
To compare the two forces, we first compute the electrostatic force using Coulomb’s law, F=k∣q1q2∣r2 F = k ∣ q 1 q 2 ∣ r 2 . We then calculate the gravitational force using Newton’s universal law of gravitation. Finally, we take a ratio to see how the forces compare in magnitude.
Is the force between two electrons attractive?
Electric field
If two charges have the same sign, the electrostatic force between them is repulsive; if they have different sign, the force between them is attractive .
What is the force between electron and proton?
The magnitude of charge on electron and proton is same and equal to 1.6×10−19C i.e. q1=q2=1.6×10−19C. The distance between the two charges is r=0.05 nm=0.05×10−9m . Hence, the electrostatic force of attraction between a proton and an electron in a hydrogen atom is 9.216×10−8 N .
What factors affect electric force between two objects?
Both gravitational and electric forces decrease with the square of the distance between the objects , and both forces act along a line between them. In Coulomb’s law, however, the magnitude and sign of the electric force are determined by the electric charge, rather than the mass, of an object.
What are the similarities and differences between electric force and gravitational force?
| Similarities Differences | Both have fields Electric force can be both repulsive and attractive but gravity only attracts | Both have potential lines Electric force results from charge but gravitational force results from mass |

What are the 4 fundamental forces?
Forces and carrier particles
There are four fundamental forces at work in the universe: the strong force, the weak force, the electromagnetic force, and the gravitational force . They work over different ranges and have different strengths. Gravity is the weakest but it has an infinite range.
What forces do leptons experience?
Lepton, any member of a class of subatomic particles that respond only to the electromagnetic force, weak force, and gravitational force and are not affected by the strong force.
What are the two types of charge?
Electric charges are of two general types: positive and negative . Two objects that have an excess of one type of charge exert a force of repulsion on each other when relatively close together.
Can two electrons attract each other?
Due to electrostatic repulsion the two electrons will repel each other as they both possess similar charges (lets leave gravitational attractive force out of the picture).
Why is attractive force negative?
That’s all right,but I want to know whenever we use a work done by an attraction force we use a negative sign,viz: the gravitational potential.It is written in books that the gravitational potential is negative because the work to bring an object from infinity to the gravitational field is done by the gravitational ...
What are attracted to electrons?
All negatively charged electrons are attracted towards any positive charge , and a major source of positive charges are the protons at the center of the quantum atom. Shared electrons in a covalent bond, therefore, are pulled towards the positively charged protons at the centers of the two atoms.
Who discovered the electron?
Although J.J. Thomson is credited with the discovery of the electron on the basis of his experiments with cathode rays in 1897, various physicists, including William Crookes, Arthur Schuster, Philipp Lenard, and others, who had also conducted cathode ray experiments claimed that they deserved the credit.
Why do electrons and protons not attract?
Protons and electrons stick to each other as much as they can, but kinetic energy and quantum mechanics keep them from holding still. Protons and electrons are attracted to each other because the positive electric charge of the proton is attracted to the negative charge of the electron .
Is proton proton attractive or repulsive?
The protons in a nucleus have two forces to contend with, the electromagnetic force which is repulsive as you suggest, and also the strong nucleon-nucleon force which is not only attractive but also much stronger than the other.
