The reside in the nucleus of atoms and are tightly bound; they will never leave an alom as sa result of electrostati procedures On the other hand, are located outside the nucleus and ate easily removed from or added to aloms. As an object begins to gain or lose from its atoms, it becomes positively or neg atively charged. A A positively charged object has more than negatively charged object has more than Consider the following process: An uncharged metal pop can is attached to a Styrofoam cup (which acts as an insulating stand). A negatively charged balloon is brought near the pop can. While the balloon is held near, the can 15 touched.When the can is pulled away, the pop can is charged. 2.

Answer 2

1. This question is about static electricity and charging by induction. The blanks need to be filled with words out of 'electrons' and 'protons'. Each one has its properties like 'positively ' or 'negatively' charged, and knowing those properties, can be filled two blanks at a time. 2. For choice questions (2.-7.) It's key to understand what charges are in play: the positive in protons or the negative in electrons. Consider this: will the electrons move and add excess negative charge or will the removing of them result in positive charge? Answering question 7, if a negatively charged object is used, what will the charge be on the object it's inducing?Past these tips, read the provided lesson on Charging by Induction (source: The Physics Classroom) if you feel you need more understanding of it.
