I was reading my physics books. And then a question came across my mind. Now here the the definition of coulomb. Electric charge measured in units of coulombs. It takes about 6*10^18 electrons. So the question is did the electric charge only consists of electrons.

What are the magnitude and direction of the electric field that will balance the weight of (a) an electron and (b) a proton? Please I am getting confused in this question. I want help with complete explanation. Thanks in advance. How will it done..?
