Explanation:
The mass of the each ball is
The negative charge on each ball is
Now we are told that the lower ball is restrained from moving this implies that the net force acting on it is zero
Hence the gravitational force acting on the lower ball is equivalent to the electrostatic force i.e
=>
here k the the coulomb's constant with a value
So
