Are forces always attractive?
In the case of gravity, mediated by spin 2 particles, charge is mass, which is always positive. Thus, q1q2 is always greater than zero, and gravity is always attractive. For spin 0 force mediators, however, there is no restriction on the charges and you can very well have repulsive forces.
Which non contact force can only ever be attractive?
Unlike the other two fields, which can involve both attraction and repulsion, gravity only acts by attraction.
Is gravitational force an attractive or a repulsive force?
Gravitational force –an attractive force that exists between all objects with mass; an object with mass attracts another object with mass; the magnitude of the force is directly proportional to the masses of the two objects and inversely proportional to the square of the distance between the two objects.
Which of these is always attractive in nature?
The gravitational force is the mutual forces between any two bodies of the universe. It is always attractive in nature.
Is electric force attractive or repulsive?
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. This called Coulomb’s law and was the first attempt to understand the electric force.
What is an attractive force?
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.
Is magnetic force is always attractive in nature?
the gravitational force is always of attractive nature while the electrostatic force and the magnetic force cn be either attractive or repulsive….
Why gravitational force is always attractive force?
Gravitational force is always attractive based on the traditional understanding of matter, which has a positive mass.
