If the charges are at rest then the force between them is known as the electrostatic force.The electrostatic force between charges increases when the magnitude of the charges increases or the distance between the charges decreases. The force exerted by on is given by Coulomb's law: q1 q2 r q1 q2 12 12 2 ˆ e qq k r F= r G (2.2.1) where ke is the Coulomb constant, and rrˆ = /r G is a unit vector directed from to , as illustrated in Figure 2.2.1(a). According to Gauss’s law, the total of the electric flux out of a closed surface is equal to the charge enclosed divided by the permittivity. The value of = 9 × 10 9 Nm 2 /C 2 Relative permittivity or dielectric constant, Learners need to understand that it is only the magnitude of the charge that needs to be inserted into the Coulomb’s law equation. If you don't see any interesting for you, use our search form on bottom ↓ . 1.15 Applications Of Gauss’s Law 1.15.1 Field due to an infinitely long straight uniformly charged wire 1.15.2 Field due to a uniformly charged infinite plane sheet 1.15.3 Field due to a uniformly charged thin spherical shell. COULOMB'S LAWCharles Augustin de Coulomb, in 1785 through his experiments, found out that the two point charges 'q1' and 'q2' kept at a distance 'r' in a medium exert an electrostatic force 'F' on each other. II. Coulomb’s Law. Share. While applying Coulomb’s Law to find out the force between two point charges, we have to be careful of the following remarks. Insulators: Resist the passage of charges.

Force between two electric point charges at rest is , where q 1 and q 2 are the charges in coulomb, r is the distance between the point charges in meter, ε 0 is called the permittivity in free space. There is an exception: when the charge is distributed uniformly over a spherical surface, the force on a point charge outside the surface may be computed from Coulomb’s law by treating the charge on the sphere as if it were concentrated at the centre. Charging by induction and grounding: Charge is often an efficient way of charging a conductor. This is similar to when you run a comb through your hair…it will then attract bits of lint or dust.
