Which observation provides evidence of the force that the balloons exert on each other over a distance because of their charge?The amount of rubbing with the wool cloth can change the amount of charge. Both Balloon 1 and Balloon 2 are pulled downward by the force of gravity. Moving Balloon 1 can make Balloon 2 move without the balloons touching. The charge on the balloons gets weaker over time until there is no charge.
