Final answer:
To calculate the net electric field at x = -4.04 cm, information on all charges and their positions is necessary; the details provided are insufficient for an accurate answer.
Step-by-step explanation:
The question seeks to determine the net electric field at a certain point, specifically at x = -4.04 cm. This involves understanding the principles of electric fields, which are vector quantities defined by both magnitude and direction. Electric fields result from electric charges and are depicted by electric field lines. For a negative charge, such as described in the referenced scenario with electric field lines pointing toward the center, the direction of the electric field is towards the charge. To provide an accurate answer regarding the net electric field at a specific point, detailed information about all charges involved and their positions is required. However, the information given is insufficient to determine the net electric field at x = -4.04 cm since no context or additional details about other charges and their positions are provided.
