# How do you calculate attractive forces?

Contents

The mathematical formula for gravitational force is F=GMmr2 F = G Mm r 2 where G is the gravitational constant.

## How do you find the force of attraction in physics?

Answer: To get the attraction force between these masses we use the above equation, where m1 = 800 kg, m2 = 500 kg, d = 3 m. F = 2.964*106 N. 2) At what distance are two masses of 60 kg and 70 kg, if the magnitude of the force with which they are attracted is 9*104 N?

## How do you calculate attractive energy?

The energy of attraction of a two-particle system having the opposite type of charges with equal magnitude q placed at a distance of separation d is U=−kq2d U = − k q 2 d .

## What is attractive force measured in?

The weight of an object is the gravitational force between the object and the Earth. The more mass the object has the greater its weight will be. Weight is a force, so it’s measured in newtons. All objects have a force that attracts them towards each other.

## What is attractive force in physics?

Definitions of attractive force. the force by which one object attracts another. synonyms: attraction. Antonyms: repulsion, repulsive force. the force by which bodies repel one another.

## What is attraction force?

Force of attraction is a force that pulls the body near due to its attraction. … Some of them are magnetic force, electric force, electrostatic force and gravitational force. Gravitational force is very well-identified instance force of attraction as it draws objects towards itself regardless of its distance.

## How do u calculate force?

The force formula is defined by Newton’s second law of motion: Force exerted by an object equals mass times acceleration of that object: F = m ⨉ a. To use this formula, you need to use SI units: Newtons for force, kilograms for mass, and meters per second squared for acceleration.

## How are attractive and repulsive forces distinguished when calculating forces?

The Coulomb force between two or more charged bodies is the force between them due to Coulomb’s law. If the particles are both positively or negatively charged, the force is repulsive; if they are of opposite charge, it is attractive.

## How do you calculate electrostatic attraction?

Calculate the electrostatic force using the formula: F = K[q1 x q2]/D^2 where K is coulombs constant, which is equal to 9 x 10^9 Nm^2/C^2. The unit for K is newtons square meters per square coulombs.

## How are ionic bonds formed and what is the attractive force?

ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. … The atom that loses the electrons becomes a positively charged ion (cation), while the one that gains them becomes a negatively charged ion (anion).

## What is the value of G universal gravitational contact?

G is called the constant of gravitation and is equal to 6.67 × 1011 newton-metre2-kilogram2.

## What is force of attraction in chemistry class 9?

Intermolecular force: Intermolecular forces are the forces of attraction or repulsion which act between neighboring particles (atoms, molecules, or ions ). … The intermolecular/interatomic force of attraction is maximum in solids. Due to this, the molecules of solids are closely packed.

## Which of the following is correct order of force of attraction?

The forces of attraction are the strongest in solids, followed by liquids and the weakest in gases. Oxygen is a gas, water is a liquid and sugar is a crystalline solid. So the increasing order of forces of attraction is Oxygen
