Please answer all the questions and circle the answer.

1) Just choose the options fo the question below. (options are less than or greater than, true or false, and North, South, East, and West.

The electric field from two charges in the plane of the paper is represented by the dashed lines and arrows below. R '. r' \\ I J / ' I I ' l \\ a ' I r z' ' . t . I, I t t t t . \\ I \\ ' I \\ 2 I elect a response for each statement below. (Use 'North' towards top of page, and 'East' to the right) Lessthan The magnitude of the E-field at L is than at J. False a The sign of the charge on the right is positive. True 9 The force on a () test charge at S is zero. Greaterthan a The magnitude of the charge on the right is that on the left. East a The force on a () test charge at K is directed North 9 The force on a () test charge at N is directed West a The force on a (+) test charge at K is directed The image shows the field lines of two charges. V ' L 0,0 020 A A Left Between Right Which one of the charges has the bigger magnitude? Correct: Charge Q1. Incorrect Charge Q2. Incorrect Same magnitude. You are correct. Your receipt no. is 163-8131 @I Prewous Tries Which of the charges are positive? 0 Only charge Q1. Only charge Q2. Both of them. None of them. Incorrect. Tries 2/2 Previous Tries At which location (not necessarily within the figure) would the electric field be zero? Left of the charges. Between the charges, closer to charge Q1. Between the charges, closer to charge Q2. Right of the charges. Nowhere. Submit Answer Tries 0/2 Other than at innity, at which location (not necessarily within the gure) would the electrostatic potential be zero? Left of the charges. Between the charges. Right of the charges. Nowhere. A proton and an electron form a dipole separated by 1.3e10 m along the y-axis centered at the origin. What is the magnitude of the net electric eld at 7.3e10 m on the yaxis? 9.78x108 N/C You are correct. Your receipt no. is 163-8484 W What is the magnitude of the net electric field at 7.3e-09 m on the y-axis? 9.98E6N/c Submit Answer Incorrect. Tries 5/99 Previous Tries What is the magnitude of the net electric field at 7.3e-09 m on the y-axis if the charges are separated by 1.3e-09 rn? 9.78x106 N/C You are correct. DrouiAIlr Trice Match the syntax with its description: A Divides x by two. B Raises x to the second power. C Multiplies x by 2. B: X**2 A: X/2 C: X*2 You are correct. Your receipt no. is 163-570 (? Previous Tries Put the following lines into a glowscript script and run them: theta = 6. 0288 particle_position = vector(1.0, 1. 0,0) obs location=vector (cos (theta), sin(theta), 0) r=obs location-particle_position rmag=sqrt (r. x**2+r. y**2+r. z**2) rhat=r/ rmag Check all of the variables that are vectors: True: r False: rmag True: rhat True: obslocation True: particle_position False: theta You are correct. Your receipt no. is 163-9567 (2 Previous Tries (c. ) What is the length of the vector r? 2 Feel free to put a print statement in your code. Also note that length and magnitude are synonyms
