Electrical force b/w two charges is given by Coulomb's law. It states that the force 'F' b/w two charges 'q1' & 'q2' separated by a distance 'r' is directly propotional to the product of magnitude of two charges & inversely propotional to square of distance b/w them i.e; F ¤ q1q2/r^2 => F = Kq1q2/r^2 where K = 1/4 pi epsilon nought = 9 *10^9 N m^2/C^2 is called dielectric constant of the medium and epsilon nought =8.854*10^-12 C^2/N m^2 is called absolute permitivity of free space. If the charges are in medium, then epsilon nought is replaced by epsilon.

What do electric forces act between?
Electrical forces act between separated charges.
How does distance effect the electric force between two objects?
Electric force can act at a distance, but is stronger when objects are closer. the electric force is larger the closer the two objects are The electric force varies with the distance between the charges. The closer they are, the stronger the force. The farther apart they are, the weaker the force.
Why don't the attractive and repulsive forces cancel outwhen a negatively charged rod is brought close to some small pieces of neutral paper. The positive sides of molecules in the paper are attracted?
The The molecules in the paper will orient themselves so that the positively charged sides point towards the rod and the negatively charged sides point away. Since the electrical forces decreases with increasing distance the nearer positive charges experience a stronger force than the more distant negative charges. As a result, the net force will be one of attraction.
Why are materials magnetic?
the materials are magnetic because of electromagnetic forces and this force is produced because of presence of positive and negative charges in them
Forces of attraction between molecules tend to be strong?
Atoms held together in molecules are done so by intramolecular forces, which include ionic, covalent, and metallic. These depend upon the electroegativty of the specific atoms being bonded and how many bonds they have. You might mean intERmolecular forces, which bind multiple molecules in solution. I listed them below in order of descending strength: Ion-ion, hydrogen bonds, dipole-dipole, London dispersion forces.
What do electric forces act between?
Electrical forces act between separated charges.
How do forces between between electrical charges differ from forces between masses?
Forces between electrical charges are governed by Coulomb's law, which is based on the quantities of the charges involved and their distance apart. Forces between masses are governed by the law of gravity, which is based on the masses of the objects and their distance apart. Both forces decrease with distance, but the electrical force can be attractive or repulsive depending on the charges, while gravity is always attractive.
Are the coulomb forces between electrical charges conservative?
yes i think that electrical are to much
Does gravitational and electrical forces depend on a physical property of objects?
If there is a single property of physical objects upon which both electrical and gravitational forces depend it is the property of mass. Without mass, there is no gravity. Likewise, without mass, the are no sources for electrical fields or apparatus for separating and transmitting charges.
When the distance between two charges is three time far apart electrical force between the charge is?
Electrical forces are inversely proportional to the square of the distance separating the charges.
When two opposite electrical forces are near each other what will happens?
When two opposite electrical forces are near each other, they will attract each other. This attraction is due to the presence of opposite charges, which exert a force on each other. The strength of the attraction will depend on the magnitude of the charges and the distance between them.
Why is static electricity called static if it moves so much?
The attractive and repulsive forces between charged particles are there, whether the charged particles move or not. They do not depend on the movement of the charges. This is in contrast with other electrical phenomena, which only appear when there is a movement of charges.
How are electrical charges affect by position and strength?
Electrical charges experience forces that depend on their position and the strength of the electric field. Charges closer together experience stronger forces of attraction or repulsion due to the electric field being more intense. The strength of the electric field decreases with distance from the source charge, affecting how charges interact with each other based on their positions.
What is a main difference between gravitational and electr onic forces is that electrical forces?
The main difference between gravitational and electronic forces is that electrical forces originate from the interaction between charged particles, such as electrons and protons, while gravitational forces arise from the mass of objects. Additionally, electrical forces can be attractive or repulsive based on the charges involved, whereas gravity is always an attractive force between masses.
Why does the gravitational force between the Earth and moon predominate over electrical forces?
Between the Earth and the Moon, for example, there is no net electrical force. So the weaker gravitational force, which is only attracts, remains as the predominant force between these bodies.
What is the difference between electeical forces and gravitational forces?
-- Electrical force only cares about the charge on two objects, and ignores their mass. Gravitational force only cares about the mass of two objects, and ignores their charge. -- Electrical force can be attractive or repulsive. Gravitational force can only be attractive.
Can a electrostatic act on a distance?
Yes, electrostatic forces can act over a distance. These forces result from the interaction between electrical charges and can cause attraction or repulsion between charged particles, even when they are not in direct physical contact. The strength of the force decreases as the distance between the charges increases.
