tem 4 Draw the vector starting at P Review Learning Goal: To practice Problem-Solving Strategy 23.2 for continuous charge distrbution problems A straight wire of length L has a positive charge distributed along its length. Find the magnitude of the electric field cue to the wire at a point located a distance d from one end of the wire along the line extending from the wire. (Figure 1) No elements selected Figure 1 of 1 L- Segment i, Charge ΔΟ Select the elements from the list and add them to the canvas settirg the appropriate attributes.

Part B With reference to the coordinate system used in the previous part, which component, if any, of the electric field due to the total charge is zero at P? the y component the x component both the x and y component neither the x nor the y component Correct Since the point at which you want to calculate E lies on a straight line extending from the wire, E must be directed along the same line. Therefore, by choosing the x axis to be parallel to the wire, as we did in Part A, we simplified the problem: Now the y component of the field at P is zero and the magnitude of E is simply given by the magnitude of its x component

▼ Part C Find Enet, the magnitude of the electric field at point P due to the total charge. Express your answer in terms of some or all of the variables Q, L, and d, and the constants T and eo View Available Hint(s) Enet d(d+L) Previous Answers

Part D magine that distance d is much greater than the length of the wire. Intuitively, what should the magnitude of the electric field at point P be in this case? Express your answer in terms of some or all of the variables Q and d, and the constants π and Co. The variable L should not appear in your answer.
