The distance between the two electrons will be .
Explanation :
We know charge carried by 1 electron =
And also mass of one electron =
Since the both electrons are in equilibrium due to gravitational and electrostatic forces , so the equilibrium condition will be :
Or,
Or,
Or,
Or,
Or, r =
So,the distance between two electrons to be in equilibrium is .
