Answer:
-The amount of electric force depends on the amount of charge
-Adding more charge to either balloon caused a greater repulsive force.
-If the one balloon has more electric charge, that causes a greater electric force on both balloons, causing them to deflect equally.
Explanation:
According to Coulomb's law of electrostatic force between two charged masses, the force of attraction is proportional to the product of the charges on the masses. This means that the more the charge on the masses, the more the electric force on them. And adding more charge to either balloon will only cause the balloons to repel each other with a greater amount of force.
The electric force between two charged masses is of the same magnitude both ways, regardless of the individual charges on the masses. This justifies the fact that If one balloon has more electric charge, it will cause a greater electric force to be exerted between both balloons, causing them to deflect equally.
