Question 6 (3 Points) This assignment is set up for sequential assessment. Complete each question and submit the answer before moving on to the next question. Correct answers for each question will be made available once the maximum number of attempts have been made for each submission. Electric Field - 3 Point Charges on a Triangle Case 2 You will use a new approach to solve the previous problem in which three point electric charges are on a Triangle Case 2. Make sure the angle setting in your calculator is "Degree". sin30º = 0.5 1 o d12 d23 a A 0 91 d13 93 Before putting anything at the origin o, 91 = +4.0 uc, q3 = -5.0 MC, 14C, = 10-6 013 = 0.20 m, angle a = 39° use k = 9.00 x 10°N/(m2c2) for Coulomb's constant Notice that point A in the figure is exactly halfway between charges 91 and 93. Calculate the distance d12 between charges 91 and origin O. The distance. d23 between charge 43 and the origin 0 = 012. Keep 4 decimal places. Enter a number m Submit (5 attempts remaining) (a) Calculate the magnitude of the electric field E1 at the original O produced by charge q1. Remember: MAGNITUDE is never negative. Don't use scientific notations. Round to integers. Enter a number N/C Submit (5 attempts remaining) What is the direction of the electric field E1 at the original O produced by charge q1? Report the direction by a counterclockwise angle from the +x axis. Round to integers. Enter a number Submit (5 attempts remaining) (b) What is the magnitude of the electric field E3 at the original O produced by charge q3? Remember: MAGNITUDE is never negative. Don't use scientific notations. Round to integers. Enter a number NC Submit (5 attempts remaining) What is the direction of the electric field E3 at the original O produced by charge q3? Report the direction by a counterclockwise angle from the +x axis. Round to integers. Enter a number
