For Question 13: In our book, Eq. (23.11)gives a linear restoring force, and thus simpleharmonic motion, wheny << R.001(part1of2)10.0pointsConsider three charges arranged as shown.-++4.4 cm3.1 cm2μC7.8μC1.8μCWhat is the electric field strength at a point1.3 cm to the left of the middle charge? The 2.Answer in units of N/C.002(part2of2)10.0points What is the magnitude of the force on a 1.8μCcharge placed at this point?Answer in units of N. 10.0points 2.Answer in units of N/C.004(part1of2)10.0points A rod of length 16 m with uniform charge per unit length 53 C / m, is placed a distance 6 m from the origin along the x axis. A similar rod with the same charge is placed along the y axis as in the figure. Consider only an infinitesimal segment of length Δ x on the horizontal rod, which is placed along the x axis, with the segment at a distance x from the origin.
