Coulomb's law can be stated as a simple mathematical expression. The scalar form gives the magnitude of the vector of the electrostatic force F between two point charges q1 and q2, but not its direction. If r is the distance between the charges, the magnitude of the force is The constant ke is called the Coulomb constant and is equal to 1/4πε0, where ε0 is the electric constant; ke ≈ 8.988×10 N⋅m ⋅C . If the product q1q2 is positive, the force between the two charg… Webelectrostatics, the study of electromagnetic phenomena that occur when there are no moving charges—i.e., after a static equilibrium has been established.

WebAnswer (1 of 2): I think you are talking about 1/4πε0 in S.I unit it has value 1/4πε0 = 9 x 10^9 kg m^3 s^-2 c^-2 In CGS system it has value 1/4πε0 = 1 you can convert by changing kg to g , m to cm , & C to esu (1 C = 3 x 10^9 esu) . Thanks WebThis equation is known as Coulomb’s law, and it describes the electrostatic force between charged objects. The constant of proportionality k is called Coulomb’s constant. In SI …
Web24 feb. 2012 · ‘k’ is a constant that depends on the medium in which charged objects are placed. In S.I. system, as well as in M.K.S. system k=1/4πε o ε r. Hence, the above equation becomes. The value of ε o = 8.854 × 10 -12 C 2 /Nm 2. Hence, Coulomb’s law can be written for medium as, Then, in air or vacuum ε r = 1.
