Yes, the balloon's motion can be affected after creating charges on its surface. When an object, like a balloon, becomes charged—either positively or negatively—it generates an electric field around it. If you then bring the charged balloon close to other objects (charged or neutral), the interactions between the electric fields can cause forces to act on the balloon.
For example:
- If a charged balloon is brought near a neutral object, it can induce a charge on that object and create an attractive force.
- If the balloon is near another charged object with the same type of charge, it will experience a repulsive force.
These interactions can alter the balloon's trajectory, acceleration, and overall motion depending on the nature of the charges and the distances involved. Therefore, the creation of charges on the balloon does affect its motion.
