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.
The 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).
Electrical forces act between separated charges.
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.
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.
the materials are magnetic because of electromagnetic forces and this force is produced because of presence of positive and negative charges in them
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
Gravitational forces are always attractive. Electrical charges are repulsive for same-type charges, and attractive for opposite-types.
Electrical forces act between separated charges.
The attractive forces are electrical forces between opposing charges.
Forces between electrical charges.
yes i think that electrical are to much
Electrical forces are inversely proportional to the square of the distance separating the charges.
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.
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.
Electrostatic force — APEX
mainly positive and negative charges
Electromagnetic.
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.
