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.

∙ 13y agoThe magnitude of the force between two charges depends on
-- the product of the magnitudes of the two charges, and
-- the distance between the centers of the charges.
The direction of the force depends on whether the signs of the charges
are the same (repelling force) or opposite (attracting force).

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
Is electric force a contact force?
Subatomic particles - as well as atoms and molecules which are made up of such particles - have a property called "electric charge". This charge can be positive, negative, or neutral (no net charge). There is a force among such charges; this force is attractive for opposite charges, and repulsive for like charges. In other words, a positive charge and a negative charge attract one another; while two positive charges, or two negative charges, push away from one another.watts
How do forces between between electrical charges differ from forces between masses?
Gravitational forces are always attractive. Electrical charges are repulsive for same-type charges, and attractive for opposite-types.
What do electric forces act between?
Electrical forces act between separated charges.
What are the attractive forces of plasma?
The attractive forces are electrical forces between opposing charges.
What is the definition of eletrical force?
Forces between electrical charges.
Are the coulomb forces between electrical charges conservative?
yes i think that electrical are to much
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.
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.
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.
What of the four fundamental forces is an attraction between opposite charges?
Electrostatic force — APEX
What are the causes of magnetic and electrical forces?
mainly positive and negative charges
What are the forces between charges?
Electromagnetic.
Does the coulomb force that one charge exerts on other charges change if the other charges are brought nearby?
First of all, one charge doesn't exert force on other charges. The forces always occur in pairs ... a pair of equal and opposite forces between every two charges. The strength of those forces is proportional to the product of the two charges, and inversely proportional to the square of the distance between the two charges. So yes, if the distance between two charges were to change, then the coulomb force between them would change. If new, additional charges happen along, then there are forces between every two charges present. The forces between the original two don't change.
