Question

A rod of length 14 m with uniform charge per unit length 78 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 delta x on the horizontal rod, which is placed along the x axis, with the segment at a distance x from the origin. Determine the magnitude of the electric field E rightarrow rod 1 at the origin due to the entire horizontal rod. The value of the Coulomb constant is 8.98755 times 109 N middot m2 / C2. Answer in units of N / C Determine the magnitude of the electric field E rightarrow tot at the origin due to both rods. Answer in units of N / C

Explanation / Answer

E = /2or

   = 78/2*3.14*8.87 *10^-12 * 13

= 466.5 *10^-9 N/C
