    A/t coulombs law F is directly proportional to product of magnitude of two charges and inversely proportional to distance between them... Remove proportionality sign and put constant k... F=Kq1q2/r^2 In CGS system, k=1 F=q1q2/r^2 In SI system, k=1/4(pi)Eo Eo = Relative electrical permittivity of free space F=q1q2/4(pi)Eor^2 ...Hope it helps...

    1Thank You
