Question

The net electric force acting on each of the three objects below is sketched as a green arrow. For example, if the green arrow points to the left the object feels a net electric force pushing it to the left. If there is no green arrow, the object feels no net electric force. Use this information to assign an electric charge to each object. That is, decide whether each object has a positive electric charge, a negative electric charge, or is neutral. olo Note for advanced students: there may be more than one correct answer. Ar

Explanation / Answer

Always remember like charges repel each other and unlike charges attract each other. So as we can see that the two exteme objects has net direction of force towards central object which means that the two extreme object have same charge and middle object has opposite charge and so there can be two possibilities which are:

1.middle object is negatively charged while two extreme objects have positive charge

Or

2 .middle object has positive charge while other two extreme objects have negative charge.
