Electric forces in between two charges depend on1.

You are watching: What do electric forces between charges depend on?

the distance between the charges2. lot of fee they both have3. medium in which they space kept4. Nature that the chargesElementary particles kind the issue surrounding us. The three most common elementary particles room electrons, protons and also neutrons.These primary school particles possess distinctive physics properties like mass, electric charge and spin. Because of these physical properties, elementary corpuscle exhibit physics phenomenon prefer gravitational pull and electrical forces. For example,Due come the mass of elementary school particles, lock exert a gravitational pull on every other.Thus, an electron with me= 9.10940 x 10-31 kg attracts one more electron inserted 1 centimeter away v a gravitational force of 5.5 x 10-67 N.But, perform electrons really lure each other? No, lock don’t. Instead, they repel each other. This repulsive pressure is because of the charge possessed by the elementary particles.

What is an electric charge?

Electrical fee is the basic physical building of a issue that reasons it come experience force when put in one electromotive field.A charge can be of 2 kinds; positive and negative.A optimistic charge signifies the the electric force exerted is attractive, while a an unfavorable charge exerts a repulsive force.SI unit of fee is coulomb abbreviated as $C$.A charge on a proton is thought about to it is in positive, while that on one electron is taken as negative. A ghost is an uncharged primary school particle.

Why do two electrons repel each other?

Though 2 electrons be separated by a 1 cm street exerts a gravitational pressure of 5.5 x 10-67 N due to their mass. Yet, as result of the negative electrical charge between the 2 electrons, castle exert a repulsive force of better magnitude on each other.Therefore, 2 electrons placed at a 1 cm street in an electric field loss each other with a 2.3 x 10-24 N force.

What factors determine the electrical forces between the charges?

French physicist Charles-Augustin de Coulomb in 1915 defined the factors influencing the electrostatic force between the fee particles in the type of Coulomb’s law.Coulomb’s law quantifies the size of the force between the charged particles.It says that “the size of the electrostatic force in between two electrically charged particles is straight proportional to the product that the size charges and inversely proportional come the square of the distance between them. Mathematical the is to express as,$F \propto \fracq_1q_2r^2$Therefore,$F = k\fracq_1q_2r^2$Where,q1 and q2 room the fees on the particles.r is the separation in between themk is a proportionality constant.The worth of k is same to 1/4πε0. The continuous ε0 is dubbed the permittivity of cost-free space and its worth is 8.85419 x 10-12 C2 N-1 m-2 in SI units.Therefore the value of k in SI systems is identified as 8.98755 x 109 N m2 C-2.The worth of k is continuous for a details medium.Thus, the factors affecting the electrical force in between charges can be summarized as :(i) magnitude of the charges current in the system.(ii) distance separating the fees in the system.(iii) The tool separating the two electrically fee particles.(iv) Nature of the charges: hopeful or negative.

Limitations of Coulomb’s Law

Coulomb’s law is acquired under certain assumptions. The Coulomb’s legislation is not applicable under complying with conditions:If the charges space mobile. Because that the validity of Coulomb’s legislation the charges need to be stationary v respect to every other.If the electric charges have actually an asymmetrical charge distribution. For the validity of Coulomb’s legislation charges must have actually a spherically symmetric distribution.If the dues overlap v each other. For the validity the Coulomb’s regulation they must be distinct suggest charges.Related Articles
