Answer:
1.43 x 10¹⁷.
They will accelerate away from each other.
Explanation:
Force on each charged sphere F = mass x acceleration
= 8.55 x 10⁻³ x 25 x 9.8
= 2.095 N
Let Q be the charge on each sphere
F = 
2.095 =
Q² =
Q = 2.289 X 10⁻⁶
No of electrons = Charge / charge on a single electron
= 
=1.43 x 10¹³.
They will accelerate away from each other.
