일반물리학 2 — Electric Fields: Problem 10

10 In Fig. 22-26, positive charge \(q = 9.25 \text{ pC}\) is spread uniformly along a thin nonconducting rod of length \(L = 16.0 \text{ cm}\). What are the (a) magnitude and (b) direction (relative to the positive direction of the \(x\) axis) of the electric field produced at point \(P\), at distance \(R = 6.00 \text{ cm}\) from the rod along its perpendicular bisector?
