(adsbygoogle = window.adsbygoogle || []).push({}); about coloumb??????

i wonder why two point charge whose magnitude 0 and +q(or smt different from zero charge) exert a coloumb force to one another

.formula says there shoud be no force acting to each other(because of multiplication q1.q2=0) but there is an atraction between them .

if this force exist what the magnitude is.

thanks for your reply..
