How Strong is the Coulomb Force Relative to the Gravitational Force ? Compare the electrostatic force between an electron and proton separated by 0.530 × 10 − 10 m with the gravitational force between them. This distance is their average separation in a hydrogen atom.
What is the separation at which force between a proton and an electron?
How Strong is the Coulomb Force Relative to the Gravitational Force ? Compare the electrostatic force between an electron and proton separated by 0.530 × 10 − 10 m with the gravitational force between them. This distance is their average separation in a hydrogen atom.
What is the force between two protons?
Two protons are subject to two forces; the nuclear force and the electrostatic force . When they are very close together the nuclear force is dominant and when they are far apart it is the electrostatic force which is dominant. Somewhere two protons experience zero net force because the two opposing forces are equal.
What are the forces between electron and proton?
| particle-particle F g (N) F c (N) | electron – proton -1.0 x 10 – 47 – 2.3 x 10 – 8 | electron – neutron -1.0 x 10 – 47 0 | proton – proton – 1.9 x 10 – 44 2.3 x 10 – 8 |

What is the electrostatic force between an electron and a proton separated by 0.1 mm?
What is the electrostatic force between and electron and a proton separated by 0.1 mm? 2.3 × 10^-20 N , attractive.
Who was the first to measure the force between charges?
Coulomb became interested in measuring the electrical force between small charged objects and perfected a torsion balance which could reliably measure such small forces [2].
What charge is a proton?
Proton, stable subatomic particle that has a positive charge equal in magnitude to a unit of electron charge and a rest mass of 1.67262 × 10 − 27 kg , which is 1,836 times the mass of an electron.
Is proton proton attractive or repulsive?
There is much left to be done concerning this matter, but the evidence is clear that while the strong force between neutrons and protons is an attraction it is a repulsion between protons .
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 |

How far apart are two protons in an electrostatic force?
Answer:The both protons should be 5.08 meters apart so that force between them is equal to the weight of electron.
What happens when two electrons get close together?
But an interesting thing can happen when the two atoms get close together. The electron in each atom starts to notice the proton of the other atom. As a result, it becomes attracted not only to its own proton, but to the proton of the other atom as well. ... And electrons tend to repel each other .
What forces act on an electron?
The electromagnetic force binds negatively charged electrons to positively charged atomic nuclei and gives rise to the bonding between atoms to form matter in bulk. Gravity and electromagnetism are well known at the macroscopic level. The other two forces act only on subatomic scales, indeed on subnuclear scales.
What is the strongest force in an atom?
The strong nuclear force is one of the four fundamental forces in nature; the other three are gravity, electromagnetism and the weak force. As its name implies, the strong force is the strongest force of the four. It is responsible for binding together the fundamental particles of matter to form larger particles.
What is the electrostatic force that exist between proton and electron in a hydrogen atom?
| F E = 8.2 × 10 − 8 N 3.6 × 10 − 47 N | Fg ≈ 10 39 or 39 orders of magnitude |

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 happens to the force between two charges if the distance between them is cut in half?
According to Coulomb’s law, the force between two charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. If the distance between two charges is reduced by half then the force between the two charges is quadrupled .
