Hi(adsbygoogle = window.adsbygoogle || []).push({});

I was just doing my homework and i am stuck on this question. Can you please help me with this?

a) Caluculate the electric field strength E, at a point located 3.0 cm due east from a point charge q=+1.0 microcoulomb.

I know i have to use the formulas:

E = F/q

And Coulomb's law. But to use Coulomb's law you need to two charges and this question only has one. Please help on this, Thankyou.
