How far apart should the two electrons be placed, if the force each exerts on the other is equal to the weight of an electron?

Why do two electric lines of force not intersect each other?

The magnitude of force experinced by an electron placed at a point in the electric field vecE is equal to its weight mvecg . The magnitud of vecE is

If it is assumed that the charges of the earth and the sun are not quite neutralised and the net charges are of the same sign (negative) and equal in magnitude,then what should be the charge on each, so that the Coulomb force will just cancel the gravitational force? How many free electrons does this charge corresponds to?
