Z В. C. 2 m FB 3.5 m 0.5 m Fc А CG 1.5 m 1 m 0.5 m 1.5 m . For the previous image, Please answer the following questions (1) What are the coordinates of point A in the three dimensional Cartesian axis 1. (0.5, -1.5, 0) 2. (0.5, -1.5, 1) 3. (-0.5, 1.5, 0) 4. (0.5, 1.5, 0) QUESTION 2 What are the coordinates of point B in the Cartesian axis 1. (-1.5, -2.5, -2) 2. (1.5, -2.5, 2) 3. (-1.5, -2.5, 2) 4. (1.5, 2.5, 2) QUESTION 3 What are the coordinates of point C in the Cartesian axis 1. (1.5,-0.5, -3.5) 2. (-1.5, 0.5, 3.5) 3. (-1.5, -0.5, 3.5) 4. (1.5, -0.5, 3.5) QUESTION The position vector from A to B can be written as 1. AB = -21 + i + 2k 2. AB = 21 - j - 2k 3. r AB= - 2i - + 2k 4. r AB = 21 + i + 2K QUESTION 5 The position vector from A to C can be written as 1. rac = -21 - 2j - 3.5k 2. Ac = -21 + 2] + 3.5k 3. Ac = 21 - 2] + 3.5k 4. Ac = 21 + 2) + 3.5k QUESTION 6 What is the angle between FB and Fc in degrees (write your answer without units) QUESTION 7 Determine the magnitude of the resultant force in Newton if FB = 300 and Fc = 450
