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. note for advanced students: there may be more than one correct answer.

Answer

Explanation:

Step1: Recall electric - force rules

Like charges repel and opposite charges attract. A neutral object is not affected by electric forces from charged objects (except by induction in some complex cases which we ignore here).

Step2: Analyze the left - most object

Since there is no green arrow, it feels no net electric force. So it must be neutral.

Step3: Analyze the middle object

The green arrow points to the left. Assume the left - most object is neutral. If the right - most object is positive, the middle object must be negative to be attracted to the right - most object.

Step4: Analyze the right - most object

Since it repels the middle object (assuming the middle object is negative), it must be positive.

Answer:

Left - most object: neutral; Middle object: negative; Right - most object: positive
