The number of electrons in one coulmb charge is ?

One coulomb (C) of charge represents an excess or deficit of 6.24 x 1018 electrons

Explanation:

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)
