The balloon becomes negatively charged because it gains________ jumper
​

Answer 1

Answer:

1. electron

Explanation:

As we know that electrons have negative charge on them so when we run a balloon with a woolen cloth then it gets negative charge which means that it gains electrons where as protons have positive charge on them. Thus when an object is negatively charged then it either loses some protons or gains electrons.
