Answer:
The Charge will increase when they are again separated
Explanation:
Before touch the electrostatic force between them is F=
r2kq/1q 2
When they are touched, the charge will flow still they have same potential. So the average charge on each sphere is q a=2q +q2
Thus, qa>q
and qa>q2
So, after touch the force between them will be more than before.
