Question

Exercise 23.7 Hints: Getting Started | I'm Stuck A rod 12.5 cm long is uniformly charged and has a total charge of -27.0 PC. (a) Determine the magnitude of the electric field along the axis of the rod at a point 31.0 cm from its center. E = 13433.80109 X N/C It might be helpful to carefully follow through the example to make sure you understand the solution. (b) Determine the direction of the electric field along the axis of the rod at the same point. O Toward the rod along the axis of the rod Toward the rod perpendicular to the axis of the rod Away from the rod perpendicular to the axis of the rod O Away from the rod along the axis of the rod
