The gravitational force equation and the electrostatic force equation can be seen as parallel to each other.

The Universal Gravitation Equation states the force of attraction between two objects, where the mass is considered concentrated at their centers of mass:

F = GMm/R2
  • F is the force of attraction between two objects
  • is the Universal Gravitational Constant
  • M and m are the masses of the two point objects
  • R is the separation between the centers of the objects

The electrostatic force equation is called coulomb's law and states the force of attraction between particles of opposite electrical charge. It also represents the force of repulsion for like charges:

F = keqQ/r2


  • F is the force of attraction or repulsion between two electrically charged particles
  • ke is the Coulomb force constant
  • q and are point charges of the two particles
  • r is the separation between the particles

From looking at the two force equations, you can see the similarities and how gravitational force can be considered parallel to the force between two charges.

Besides being proportional to the inverse of the square of the separation, both forces extend to infinity. They also both travel at the speed of light.

One major difference is in the strength of the forces. The gravitational attraction between two electrons is only 8.22*10−37 of the electrostatic force of repulsion at the same separation. However, gravitation usually is concerned with large masses, while any large collection of charges will quickly neutralize.

Another difference between the two forces is the fact that gravitation only attracts, while electrical forces attract when the electrical charges are opposite and repel if the charges are similar. Thus, gravitation is considered a monopole force, while electrostatics is a dipole force.

However, the concept of dark energy, which seems to have an anti-gravitation force, may allow for gravitation to be both the attraction and repulsion of matter.

The gravitational force is observed to be a purely attractive force between objects with a mass. The electrostatic force between two charges can be attractive or repulsive depending on whether the charges are unlike (positive and negative) or like. Both forces are inversely proportional tp the square of the distance between the two objects involved, if the objects are point like (small). Apart from this similarity, gravitational and EM forces have very different origins at a deeper level.

Good comparison and analysis.

However, how can you say by comparing with one situation, two differents forces are alike. While concluding do some small research.

Coming to the point electromagnetic field is responsible for the tension.

current carrying wires , in which both currents move in same direction, so we know there will be a magnetic force of attraction pulling them together , as a result they also exhibit the same property as that of strings , i.e, they put tension over strings in order to try to come close to each other . So now we know that the magnetic field is also responsible for tension.

Newton's law of gravity states that the gravitational force between two bodies is proportional to the product of their masses and inversely proportional to the square 

of the distance between them.

From these you can conclude that these two forces are different, they are depending on the different parameters

Electromagnetic Forces are made when there are slight imbalances caused by small separations of charge.

The gravitational force is a force that attracts any two objects with mass. We call the gravitational force attractive because it always tries to pull masses together, it never pushes them apart
