Final answer:
The question posed is unclear as electric fields at certain (x, y) positions depend on the charge configuration around those points. The given vector describes the magnitude and direction of the electric field, not the position. For the other example, a negative charge in a constant electric field experiences force opposite to the field direction.
Step-by-step explanation:
The student's question seems to be mistakenly formatted, combining aspects of the location of an electric field with its magnitude and direction. The correct interpretation of the question is to determine the characteristics of the electric field at a given position. When it is stated that the electric field is (161,000 ᵄʹ 80,500 ķʹ) N/C, it indicates that the electric field vector has an x-component of 161,000 N/C and a y-component of 80,500 N/C. However, typically, the electric field at a specific (x, y) position is given by the configuration of charges around that point, and the question does not provide such information.
For the referenced problem number 8, a constant electric field of (4.5 × 10⁵ N/C)ķ implies that a charge placed within it would experience a force in the direction of the field. If the charge is negative, such as a -20 nC charge, the force would be in the opposite direction of the field due to the negative charge interacting inversely with the field direction.
