Force of Attraction Formula

State the Force of Attraction Formula

The force of attraction is a force that draws the body close to it due to an attraction. In nature, several attraction forces are existing in nature. These are the electric force, magnetic force, electrostatic force, gravitational force, and electromagnetic force. Gravitational force is a well-recognized force that attracts the body towards it despite the distance. Through Newton’s Gravitational force we get a lot of clarification regarding this force and how it operates. It states that the mass existing in the Universe attracts some or other mass prevalent in the universe. It validates that anything that is thrown up eventually comes down. The formula of force of attraction is based on this theory.

Representation of Force of Attraction Equation

Suppose there are two masses denoted by ma and mb parted by a space. Then the force of attraction formula is stated by 

Fg = (G mamb)/d2


F= force of attraction

G= gravitational constant

ma= mass of the first object a

mb= mass of second object b

d = distance between two objects d

This force of attraction formula physics helps in the calculation of any two bodies having a greater mass as the smaller mass is insignificant. 


The formula of force of attraction is important to understand the concept of gravity that works on the earth. Moreover, when we calculate force of attraction it also explains the gravitational phenomenon that happens in space. 

FAQs (Frequently Asked Questions)

1. What is Gravitational Attraction Formula?

In this universe, each body attracts the other body towards itself with a force known as the gravitational force. It studies the interaction between two masses. The force of attraction between two bodies states that the product of their masses is directly proportional and the square root of the distance between them is inversely proportional. 

The gravitational force of attraction formula of force is given below:

Fg ∞ (mamb)/d2


F = gravitational force between the two bodies

ma= mass of the first body 

mb= mass of the second body 

r= distance between the centre of two bodies

2. What is the electrostatic attraction formula?

In physics, the electrostatic attraction formula deals with properties and phenomena of slow-moving or stationary electric charges. Coulomb’s law describes the electrostatic phenomenon that arises from forces that electrically charged objects exert on each other. We can start with the magnitude of the electrostatic force between two points p and P. It will be safe to denote one charge as p as a test charge and another charge as P as a source charge. Once the theory is developed, more sources of charges are added. If r measures the distance between two charges, then the electrostatic attraction equation is 

F= (1/4𝜋ε0)  (pP/r2) = ke (pP/r2)

3. State the Magnetic Attraction Equation?

The magnetic force between two charges in motion is stated as an effect exerted upon any one of the charges created by the magnetic field of another charge. It mainly arises from the interaction of magnetic fields. The magnitude of magnetic force is based on the fact that how much charge is in how much motion in every object and how far apart they are. In other words, if we place a point charge q in the presence of an electric field expressed by a magnitude E(r), and a magnetic field expressed by a magnitude B(r). Then the total force applied to the electric charge q can be written as a sum of both electric force and magnetic force acting upon it. (F electric + F magnetic)

Mathematically, we can express the magnetic attraction equation as:

F= q[ E(r)+v x B(r)]
