Questions: 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. (0)

Solution Steps

Step 1: Analyze the Direction of the Net Electric Force

The direction of the net electric force on an object indicates the nature of the surrounding charges. If the force is to the left, the object is being repelled by a positive charge or attracted by a negative charge on the right. Conversely, if the force is to the right, the object is being repelled by a negative charge or attracted by a positive charge on the left.

Step 2: Determine the Charge of Each Object

  • Object with a Leftward Force:

    • If the green arrow points to the left, the object could be positively charged, being repelled by another positive charge on the right, or negatively charged, being attracted by a positive charge on the right.

  • Object with a Rightward Force:

    • If the green arrow points to the right, the object could be negatively charged, being repelled by another negative charge on the left, or positively charged, being attracted by a negative charge on the left.

  • Object with No Force:

    • If there is no green arrow, the object is neutral, experiencing no net electric force.

Final Answer

  • Object with a leftward force: Could be positive or negative.
  • Object with a rightward force: Could be positive or negative.
  • Object with no force: Neutral.

\[ \boxed{\text{Leftward Force: Positive or Negative, Rightward Force: Positive or Negative, No Force: Neutral}} \]
