Problem 23.10: Find the electric field and charge of a uniformly charged rod

Please wait for the animation to completely load.

Derive an expression for the electric field as a function of position along the line shown (position is given in meters and force is given in newtons). Restart. If the purple test charge has a charge of 1 μC, what is the total charge on the red rod in the animation?

  1. Configuration I: Field along the axis of the red rod.
  2. Configuration II: Field perpendicular to the red rod.

Remember that a test charge is defined as a charge that is so small that it does not influence other charges.
