Question

I can't figure out what I'm doing wrong. My professor posted a video showing generally how to solve the problem (without using specific numbers) and I followed all the steps.

Here is the problem and answer:

Question 4 0/18 pts A charge, q1, of +6 micro-coulombs is located at x 0, y 5.3 cm, a charge q2 of-41 micro-coulombs is located at x-0, y-3.4 cm, an unknown charge of q3, is located at x-_ 3.3 cm, y-0 cm, and a charge, q4,-10 micro-coulombs is located at x-+19.8 cm,y-O cm. The direction of the total electric force on q4 is 141.8 degrees from the +x axis, counter-clockwise. What is the unknown charge, q3, in micro-coulombs? If negative, include a negative sign in your answer. You Answered 20.489 Correct Answer 60.23 margin of error +/-10%

Answer #1

12 4 2 (3.3-t 19.8)rlo 9- 1.619,) (3.72+1 S.47)』 €4= (-12.41+90 2.6 (5.34194%。 net x-ans in conf认clock wip 38 13.11 2 3.88 .bawe assume q3 is positive and in microcoulomb so it attracts the q4 so it's direction is towards negitive X axis.

In the final step clockwise angle is taken as negitive because X component of net force on q4 is along negative X axis
