Take two balloons of equal size. Put a little water into the balloons. Blow up both the balloons and tie each one to a string. Hang the balloons 8 - 10 cm apart on bicycle spoke. Blow in the space between the balloons. What happens?
a] Both balloons come closer
b] Both balloons apart from each other
c] They first come close and they apart after
d] Nothing will happen.

Since the gravitational force between them is very small and even if there will be any accumulation of charge that will be very small. So force arising due to this two factor will be very small compared to the air resistance, so the balloon will not move. So answer d] is correct.
