which depends upon system of units and also on medium between two charges.

(1) is usually put as, where ε0 is permitivity of free space and it is given by, εo = 8.854 ×10-12 C2N-1m-2. So, the next step is How two charges interact with each other? (a) The gravitational forces are always attractive while the electrostatic forces may be attractive or repulsive. {{(9.1 \times {{10}^{ – 31}}) \times (1.67 \times {{10}^{ – 27}})} \over {{r^2}}}N$. The electrical force, like all forces, is typically expressed using the unit Newton. Q. If q1 & q2are charges, r is the distance between them and F is the force acting between them Then, F ∝ q1q2 F ∝ 1/r² ∴ F ∝ q1q2r2q1q2r2 Or F=Cq1q2r2F=Cq1q2r2 C is const. The Coulomb’s law can be re-written in the form of vectors. What is the resultant force on any one charge due to the other two? (d) Both the forces can operate in vacuum. Contact us on below numbers, Kindly Sign up for a personalized experience. Download India's Leading JEE | NEET | Class 9,10 Exam preparation app, Vector form of Coulomb’s Law – Definition | Examples. The two point charges q1 and q2 have been numbered 1 and 2 for conveneience and the vector leading from 1 to 2 is denoted by r21, The magnitude of vector r21 is denoted by |r21|. Coulombs force law between two point charges q, The above equation is valid for any sign of q. for maximum F, ${{dF} \over {dq}} = 0$ (b) Both the forces obey inverse square law i.e., F ∝ (1/r²). Since force is vector, we need to write Coulombs law in vector notation. Thus if two point charges q1 and q2 are separated by a distance r in vacuum. Welcome to Sarthaks eConnect: A unique platform where students can interact with teachers/experts/students to get solutions to their queries. In applying it to the case of extended bodies of finite size care should be taken in assuming the whole charge of a body to be concentrated at its ‘center’ as this is true only for spherically charged body, that too for a external point. Coulomb’s law is applicable to point charges only. {{{{(1.6 \times {{10}^{ – 19}})}^2}} \over {{r^2}}}$N. The Vector Form of Coulomb’s Law of Force The position vector can be used to make the calculations of Coulomb’s Law of Force more explicit. Thus,${{{F_e}} \over {{F_g}}} = 2.26 \times {10^{39}}$ i.e., electrostatic force between a proton and an electron is about 1039 times stronger than the gravitational force. For an electron-proton system, electrostatic force of attraction, ${F_e} = {1 \over {4\pi {\varepsilon _0}}}{{e.e} \over {{r^2}}} = 9 \times {10^9}. Two charged bodies experience electrostatic force and also a gravitational force on account of their masses. So, the net force on C due to charges on A and B, The vector form of the Coulomb’s law is independent of the nature of the sign carried by the charges because of the fact that both the forces are opposite in nature. The equilibrium of a charged particle under the action of Coulombian forces alone can never be stable. Coulomb’s law in vector form Coulomb’s force is a mutual force, it means that if charge ‘q 1 ‘ exerts a force on charge ‘q 2 ‘ then q 2 also exerts an equal and opposite force on q 1. In SI unit, C … Q. and the vector leading from 1 to 2 is denoted by, Coulombs force law between two point charges q, The above equation is valid for any sign of q. If they are opposite sign, F21 is along r21 that denotes attraction. If charge q 1 exerts an electrostatic force “ F12 “ charge q 2 and q 2 exerts electrical force F 21 on charge q 1. He published an equation for the force causing the bodies to attract or repel each other which is known as Coulomb’s law or Coulomb’s inverse-square law.

We denote force on q1 due to q2 by F12 and force on q2 by q1 by F21 as shown in figure. Copyright Notice © 2020 Greycells18 Media Limited and its licensors. This video explains the basic properties of electric charges. So, the net force on C due to charges on A and B. FC = FCA – FCB = 2F – F = F = 2 × 10–5 N along $\mathop {AB}\limits^ \to $. The dielectric constants of different mediums are: $\mathop {{F_{21}}}\limits^ \to $= force on q2 due to q1, $\mathop {{F_{21}}}\limits^ \to = {1 \over {4\pi {\varepsilon _0}{\varepsilon _r}}}\,\,\,{{{q_1}{q_2}} \over {r_{12}^2}}\,\,{\hat r_{12}}$, $\mathop {{F_{12}}}\limits^ \to $= Force on q1 due to q2, $\mathop {{F_{12}}}\limits^ \to = {1 \over {4\pi {\varepsilon _0}{\varepsilon _r}}}\,\,\,{{{q_1}{q_2}} \over {r_{21}^2}}\,\,{\hat r_{21}}$, $\mathop {{F_{12}}}\limits^ \to = – \mathop {{F_{21}}}\limits^ \to $ (∵ ${\hat r_{12}} = – {\hat r_{21}}$ ), Or ${\mathop F\limits^ \to _{12}} + {\mathop F\limits^ \to _{21}} = 0$.
