    Coulomb’s law states that Force exerted between two point charges:

    • Is inversely proportional to square of the distance between these charges and
    • Is directly proportional to product of magnitude of the two charges
    • Acts along the line joining the two point charges.

    F = k q1q2/r2  where k = 1/4πε0

    So, F=1/4πε0 q1q2/r2

    Here ε0 = 8.854 x 10-12 C2 N-1 m-2is called permittivity of free space.
