In the figure a thin glass rod forms a semicircle of radius r = 2.03 cm. Charge is uniformly distributed along the rod, with +q = 5.95 pC in the upper half and -q = -5.95 pC in the lower half. What is the magnitude of the electric field at P, the center of the semicircle? Answer in N/C. *Hint: consider symmetry and the direction as you solve.

R = 5 cm. Rin = 2.5 cm.  The surface charge density for both plates is 5.3 µC/m2. What is the difference in electric field at point P (12 cm up the z-axis) between these two cases?  Answer in N/C.

Three infinite parallel planes of charge have respective surface charge densities (as shown) of +σ, -σ/2, and -σ/2. Find the Electric Field for the 4 numbered positions in space.  Answer in terms of ”

Congratulations on completing Lab Quiz 1! Once  you press submit your quiz will be submitted for grading.  You will then see that your grade is muted.  Please don’t let that worry you.  It just means that I have hidden the grades.  After the deadline passes and all submissions are scored, I will review the class performance, ensure all scores are accurate and, if necessary, apply any curves.  At that point, I will un-mute/release your grades.  Because these require manual scoring, grades are not likely to be released until the middle of next week. If you wish to remove the Honorlock extension from your computer, you are safe to do so (you will just need to reinstall it before taking your next assessment).
