Expert Answer
In SI unit, we have force Fs between equal charges of Q Coulombs which are separated by r metres is given by
In CGS units (esu ), we have Force Fc between equal charges of q static coulomb which are separated by r cm is given by
in cgs units, if q = 1 static-coloumb, r = 1 cm, then force Fc = 1 dyne.
to convert 1 Coloumb to 1 static coloumb, let us assume Q = 1C and q = 1 static coloumb. Also we have to consider that the constant factor 4πε0 of SI units will be absorbed by the definition of static coloumb in cgs units. Assume the charge separation distance is 1 cm.
hence we have
then we have
