Let’s use basic knowledge of magnets to help us solve this problem. For them to stick together, one side has to be positive and one side has to be negative.
The two balloons both have a negative charge which means they won’t stick together, they will try and move away from each other.
Let’s use process of elimination.
We can eliminate B because the balloons are negatively charged, not positively charged. We can also eliminate D because when they both have the same charge, their will be no attraction.
We can also eliminate A because if we put the balloons close together, one of them won’t magically change to positive to make it attract to the negative charged balloon.
The only answer we have left is C. It is C because the balloons don’t need to touch each other for repulsion to be observed. Since both of them are negative they will want to stay away from each other.
Final Answer: C- The two balloons do not have to touch for repulsion to be observed.
I hope this helped you :)
