Refer to the following diagram depicting a uniformly charged rod holding a net charge of Q and length L for all parts of this question.

Which location for an origin makes the most sense in order to calculate the electric field from the line of charge on point P?
Incorrect Bottom of the line of charge
Incorrect Top of the line of charge
Correct: Middle of the line of charge

Which of the following is the correct set up of the integral to calculate the electric field at point, P using the origin that you indicated in the above part?

Which component of the your integral would you expect to be zero based on the electric field at point P?

Incorrect Neither should be zero.
Incorrect The x component should be zero.
Correct: The y component should be zero.
Incorrect Both the x and y components should be zero.
