Dear all: Final will be offered from 11:59 pm on 8/7/2025 to 11:59 pm of 8/8/2025. Once you start the test, you have 250 minutes to finish it. Longer duration of time is provide to you in the Final due to the consideration of taking time to type in your procedures to obtain answers for free-response questions in the boxes below the questions. Please do the following to take Final:Log into Blackboard with your STC credentials.Scroll down to Final and click on Final. ( You need to enable Honorlock to take the test. If you have any issue in lockdown browser, please contact 956-872-2598 for help.)You have 250 minutes to complete the Test.Final will cover all chapters discussed in Summer II, 2025, i.e. the discussions from Lecture_1 to Lecture_6.You can use calculators during the test but it is a closed book test. You can use the formula sheets provided by me during the test.For the first 16 multiple choice questions (Questions 1-16), you choose the correct answer for each question.For the four free response questions (Questions 17-20), you enter your solution for a question in the box (editor) below the question and you need to show the steps to obtain your answers. For the four free response questions, it would not get full credit for solutions that only have answers but not steps to obtain the answers.After you complete the test or before the 250 minutes are up, you make sure to submit your tests.You should submit all your solutions online. Please don’t email me your solutions for free-response questions via my email gxu@southtexascollege.edu. Do well in your studies.

Consider the three electric charges shown in the figure. List the charges in order of the magnitude of the force they experience, starting with the greatest. fig_q2_final.jpg

List the Gaussian surfaces shown in the figure in order of decreasing electric flux, starting with the most positive. fig_q5_final.jpg

As shown in Fig. 3.1, a 1 . 00   m  conducting rod in good contact with a frictionless conducting frame moves to the left with a constant speed 4 . 80   m s . The light bulb in the conducting frame has a resistance of 12 . 0   Ω . The entire system is immersed in a magnetic field of magnitude B → = 8 . 00 × 10 3   G  which is inclined at 30° with respect to the frame as shown in Fig. 3.1. (a) Find the induced electromotive force on the circuit. (b) What is the direction and magnitude of magnetic force exerted on the rod? To maintain the rod’s constant speed 4 . 80   m s , an external force must be applied on the rod. (c) Determine the work done by the external force after the rod is moved to the left for 5 . 00  meters. If the conducting frame is closed by a fixed conducting rod (the turquoise rod in Fig. 3.2) with a resistance of 6 . 00   Ω  to form a rectangular conducting rod as shown in Fig. 3.2, (d) what is the induced electric current through the moving conducting rod? To maintain the rod’s constant speed 4 . 80   m s , an external force must be applied on the rod. (e) Determine the work done by the external force after the rod is moved to the left for 5 . 00  meters. (Note: 1   G = 10 – 4   T ) q18_fig2.jpg
