# A thin, nonconducting rod of length \(L\) lies along the positive \(x\)-axis with its ends at the origin and at \(x = L\). The rod carries a uniform positive linear charge density \(\lambda\). Point \(P\) is located on the positive \(y\)-axis at \((0, L)\). Which of the following correctly describes the direction of the net electric field \(\vec{E}\) at point \(P\) and compares the magnitudes of its components, \(|E_x|\) and \(|E_y|\)?

![A two-dimensional Cartesian coordinate system with a horizontal axis labeled x at its right end and a vertical axis labeled y at its top end. The axes intersect at the origin labeled O. On the positive x-axis, a horizontal narrow shaded rectangle representing a rod extends from x = 0 to a vertical tick mark labeled L. Above the center of the rod sits the label \lambda. On the positive y-axis, a solid black dot sits at a tick mark labeled L, and this dot is labeled P. A vertical dashed line segment extends along the y-axis from the origin to point P. No other labels, lines, text, or axes appear.](https://nerd-notes.com/wp-content/uploads/ubq-frq-generated/stem-fig-1-1790604528-fDYmcH.jpg)
